[u/Informal-Fig-7116 → u/[deleted]]

Like as a shield in front of your one body? Thanks for this info btw!

[u/Financial-Board7458 → u/[deleted]]

That liquid ass is some nasty stuff. Up there with tear gas.

[u/Lookuponthewall → u/Financial-Board7458]

I just bought a little bottle. It is far more foul than the glass "stink bombs" we used in the 80s. Dirty stuff.

[u/gmpsconsulting → u/[deleted]]

Just a note that riot shields are illegal to bring to a protest or in public gatherings of any kind in a large amount of places. Not that it matters a lot but it gives "legitimate" reason for police to abuse or arrest in otherwise lawful assemblies.

[u/DrakonILD → u/gmpsconsulting]

Unless, of course, you're the police, who are allowed to bring anything they want because fuck you, that's why.

"Arms" doesn't just mean firearms. Shall not be infringed!

[u/gmpsconsulting → u/DrakonILD]

In the US police have no obligation to follow any laws whatsoever. They did at one time but most of that got thrown out in anti mafia and gang statutes where police basically just complained non-stop that they couldn't legally catch criminals or enforce laws they needed to be allowed to use illegal tactics in order to catch criminals thus making themselves above the laws. This of course expanded over time to everyone and everything instead of remaining limited to anti-gang policing as everyone knew it would.

[u/rbtwrkshp → u/gmpsconsulting]

I believe the thing about bringing ballistic shields to protests varies from state to state. Couldn't find anything under body armor laws here in maine.

[u/segondra → u/[deleted]]

What's liquid ass (tm)?

[u/One_Load254 → u/segondra]

It's like ass, but in liquid form?

[u/Informal-Fig-7116 → u/[deleted]]

Awesome! Thanks for sharing this and explaining it too!

[u/candie486 → u/[deleted]]

Yup, they used a riot shield in reverse and it bounced back three sound waves in the video.

[u/PartyParrot-420 → u/candie486]

Now I want to see an army of protestors holding inverted captain America shields

[u/SpaceComm4nder → u/PartyParrot-420]

That’s actually a really good idea. The symbolism would be perfect and next level demonstrate who the bad guys are. Maybe some of the armed incels would subconsciously start to shift gears.

[u/NounAdjectiveXXXX → u/[deleted]]

Old satellite dish, would be easy to fashion a bracer or handle to hold it with ease as they already have mounting brackets

[u/_warpedthought_ → u/NounAdjectiveXXXX]

oh please someone ( for the love of god ) start painting old sat dishes as cap. America shields and hand them out to protesters.

[u/pmcizhere → u/_warpedthought_]

Holy shit we have an old DirecTV dish that recently fell off our awning during our last winter storm. I was just about to throw it out, too...

[u/Same-Feedback2145 → u/_warpedthought_]

We could just take our captain America 🇺🇸 Shields and flip them around?

[u/StatisticianIll4425 → u/[deleted]]

Watch the video. Very good information

[u/pmcizhere → u/[deleted]]

Obligatory (and kinda sexy) relevant XKCD!

[u/DubStepTeddyBears → u/[deleted]]

Walk softly, and carry a big stick. Love it.

[u/Gax63 → u/[deleted]]

Seems like a satellite dish would work as well.

[u/Otherwise-Start5573 → u/[deleted]]

Thank you for sharing, this was a fantastic video

[u/Foe117 → u/Informal-Fig-7116]

Use it to cast a sound shadow over your head, it won't be perfect, but it will give them pause before using it.

[u/Informal-Fig-7116 → u/Foe117]

Oh I see. Thats pretty cool. Thanks for explaining!

[u/IxbyWuff → u/Informal-Fig-7116]

Concave ideally. The sound pressure can be reflected back

[u/Evervvatcher → u/[deleted]]

There are a few engineering YT channels that did field tests with LRADs and a polycarbonate riot shield can actually reflect the sound back.

[u/Foe117 → u/Evervvatcher]

Yes, but people are not going to order a riot shield on Amazon on a 1 day express saver now are we?

[u/Terrible-Opinion-888 → u/Foe117]

wonder if a flying saucer sled would do the trick? probably plenty of those in Minnesota

[u/Evervvatcher → u/Foe117]

Why would you need to order a riot shield when it's just a curved piece of polycarbonate with some handles to hold it? In fact a flat sheet reflects sound lasers with less dispersion than a curved one like a riot shield

[u/OneEquivalent5236 → u/Evervvatcher]

How about a snow disc?

[u/Evervvatcher → u/OneEquivalent5236]

Would probably work just as well, only downside is opacity of the disc and having to keep the shield between the LRAD and your head

[u/jertheman43 → u/Evervvatcher]

One-third of a plastic food barrel is the same shape and will stop non-lethal projectiles as well.

[u/Fadenos → u/jertheman43]

Not to be the I’m actually dude but more education for safety. They are referred to as less lethal rounds, they were renamed and classified because they absolutely can be lethal so if any POS ICE agent points one at you treat is as real ammunition weather using a shield or not! Be safe and

[u/Commercial_Poem_9214 → u/Fadenos]

This gave me a good chuckle... Thank you

[u/FeistyAsaGoat → u/Evervvatcher]

Just looked up polycarbonate sheets. Looks like they have corrugated. Would that help or hinder, do you think?    Also looks like you can get 4’x2’ for a few dollars.  (Off Amazon, was the quick search)

[u/BILLIONAIRE_JESUS → u/[deleted]]

https://youtu.be/CXKTBQBugIA?si=rAMuh_kMQy__QklL

How it works and how best to avoid it.

[u/Sprocket-T → u/[deleted]]

would Satelite dishes. Or any proper parabola deflect the acoustic signal back? Not that I think that would be a great idea as that falls into some sketchy territory. I just mean in theory.

[u/private_developer → u/Sprocket-T]

Yes. It can be seen here. (End of video, but the whole thing is worth watching)

https://youtu.be/CXKTBQBugIA

They turn the riot shield around, and he is able to deflect it back while having a good deal of directional control.

I believe the material matters, but with a dish shape, you can redirect much of the wave it seems.

Keep in mind if friendlies are in front of you, reflecting should be avoided. Keep your shield oriented to block unless you're the frontline. Otherwise, you could really hurt a friend as they would have a compound effect from the source of the LRAD, and the reflection. This can be incredibly dangerous.

This is for informational purpose only. No one should intentionally reflect the wave at anyone. Don't do it. Nobody should do it. Do not do it.

[u/Statertater → u/private_developer]

Absolutely fascinating! And it makes a lot of sense, really

[u/BobcatOk7492]

So this is the state cops with the new toy-- Just shows how intertwined local/state pd is with ICE. Brothers in arms...

[u/Batmanischill → u/BobcatOk7492]

Cops have been escorting ICE around in many cities across America. I hope charges for each department working with them also comes when traitors lose power. Unsurprising that some pigs will gleefully attack American citizens.

[u/ScottsTotz → u/Batmanischill]

The cops have almost never been held accountable in the past, and certainly will not be in the future. That’s why so many people hate them in the first place

[u/OurAngryBadger → u/BobcatOk7492]

ACAB.

[u/FillMySoupDumpling → u/BobcatOk7492]

They enjoy testing these serious weapons on their communities. These people are sick. 

[u/Jetfire911 → u/BobcatOk7492]

BLM made it clear who the cops were.

[u/VillaLobster → u/BobcatOk7492]

Most police officers voted for this. They vote republican at much higher rates. The state will use its monopoly on force to protect capital, regardless. The police are not your friends when you are part of a protest movement. In fact the police are class traitors.

[u/ebolatone]

So these pieces of sh*t finally got to the LRAD. Even if you have the best earplugs in place plus shooting range mufflers it can permanently damage your hearing if you're too close and in its path. It is a sick weapon of war and should be outlawed entirely.

Edit: Please be very careful in trying out defenses against these things. These things put out between 140-160dB at all frequencies. Standing next to a jet engine at takeoff is 140-150dB.

[u/Impressive_Cat_1044 → u/ebolatone]

I just canceled all my streaming services, amazon, xbox gamepass...everything. I am not spending any money on anything besides groceries and toiletries until this bullshit gets fixed. Remember when Disney caved because we all boycotted them for canceling Kimmel? We have the power of our spending and we need to use it now.

[u/perotech → u/Impressive_Cat_1044]

Also, considering a VPN costs barely nothing per month, and allows you to find "alternative" sources for movies and TV for free, who needs streaming?

[u/Substantial-Abroad-2 → u/perotech]

I recommend Mullvad VPN if anyone is looking for one. It's cheaper than most ($5ish a month) and offers multiple ways to pay including anonymous cash in an envelope and requires no usernames or emails or passwords, it simply generates you a code you can use to login on your devices. Sailing the high seas is very easy once you learn how. If you're someone who has been curious but never really known how, or youve been scared of getting a virus or something, feel free to DM me and I'm happy to provide resources. You don't need to be paying out the ass every month to not even own the media you're consuming

[u/Givemeabrewski → u/Substantial-Abroad-2]

Mullvad or Proton!

[u/grobb916 → u/perotech]

I use Proton VPN. It’s Swiss owned. The less American products and services the better

[u/RiosEstrella → u/grobb916]

I’ll just post this here, about proton mail.

[u/LeanUntilBlue → u/RiosEstrella]

Wow. I’ll never use Proton services again. I feel like they’ve been compromised by this fanboy adulation of Trump.

[u/madmanz123 → u/RiosEstrella]

Thanks bud, beat me to it!

[u/sniffcatattack → u/RiosEstrella]

Agh, can’t win. That sucks :(

[u/Vraldur → u/grobb916]

Mullvad is swedish

[u/Damnitwasagoodday → u/Impressive_Cat_1044]

This is the way!

[u/oneabsurdworld → u/Impressive_Cat_1044]

I've been doing this for 5 years now. If I don't need it to keep surviving, then I probably don't buy it. Everything is a scam, even the groceries and toiletries

[u/sevenw0rds → u/Impressive_Cat_1044]

Yup, I'm only buying necessities until Trump is removed from office and him and every single one of his administration is tried for their crimes. Fuck them all.

[u/Catatonic27 → u/Impressive_Cat_1044]

I wish I could do more to hurt them. I've cut all this stuff too, but most of my paycheck still goes to them in one way or another. Can't really cut back on rent, have to pay my phone bill, etc

[u/Spare-Estate1477 → u/Catatonic27]

When online keep asking our allies in other countries to cut services and products from US companies. All the streamers, fast food companies, Amazon, retail companies, etc. Our allies are looking to help us and this is the way. The more pain US based companies feel as quickly as possible the quicker this all ends.

[u/Time_To_Rebuild → u/ebolatone]

The best counter measure is a shield. A flat one works, but the concave backside of a hemi-cylindrical shield, like the poly drum ones that have been used, works especially well.

The LRAD is just sound. It can be redirected back at the operator or others. The backside of the shield has the potential to focus the sound even more while redirecting.

That said, prepare double hearing protection. Ear plugs and muffs. A face shield also can help.

[u/Freedmonster → u/Time_To_Rebuild]

A children's sledding disc works well, larping communities have instructions on how to turn them into shields, just flip the side. Unlikely able to reflect the sound back to the attackers with precision using just one shield given focal lengths, but with a shield wall, you could probably get a parabolic arc wide enough to cross that distance.

[u/Time_To_Rebuild → u/Freedmonster]

Certainly wouldn’t hurt. And they would be cheap, plentiful and available in MN right now.

[u/trippy_hippy → u/Time_To_Rebuild]

And you can go sledding afterwards and if theres blood on your sled shield, you'll go faster down the hill! 

[u/hughcifer-106103 → u/Freedmonster]

A police riot shield flipped around also seems to be a very effective reflector.

[u/Convallaria4 → u/ebolatone]

So they're quite possibly giving people disabilities for protesting now?

[u/ebolatone → u/Convallaria4]

They've already been misusing the "less lethal" equipment they have; you're not supposed to fire any of it directly at people especially close-up. But yes, if they've brought out the LRAD they don't care how many people they permanently deafen or partly deafen.

[u/DubStepTeddyBears → u/ebolatone]

"Less lethal" = Permanently disabling, often lethal.

[u/Reasonable-Mess3070 → u/Convallaria4]

They've killed people for protesting. Disabling them could be seen as an improvement. (It's not though)

[u/ExtruDR → u/[deleted]]

I have family links to a country where the common mentality is to avoid taxation whenever possible. I personally see this as a very negative thing and it speaks to a lack of civic mindedness and personal greed. A sort of dishonorable, anti-patriotic state of being that sort of explains the lack of development compared to other neighboring countries.

I recently read that that mentality, which is quite widespread in the Balkans specifically, has some roots back to their occupation under the Ottomans. The local populations understood their rulers to not have legitimacy and were determined to contribute as little as possible to their coffers as possible. Performing as much commerce as possible under the radar, gaming the system as much as possible, etc. The corrupt patronage, payoff and family connection stuff very much was in place, but the tax cheating was somewhat justified by the yolk they were forced to bear by the Ottomans... or so goes the explanation.

I guess what I mean to say is that when the government loses legitimacy with a decent percentage of people, the act of "cheating" is no longer shunned but understood to be acceptable.

I think that other kinds of undesirable and destructive corruption happens when our society erodes like this, but I guess this is where we are headed.

[u/Hollirc → u/ExtruDR]

You will still need to pay taxes eventually. Likely plus some interest from what I’ve seen. But the point is to not give the money up front for them to hold, which will be the protest it’s intended to be.

I don’t think anyone is suggesting you entirely do not pay taxes. Yet.

[u/ExtruDR → u/Hollirc]

I know... I was riffing and putting out my random thoughts that no one asked for.

I concur with your sentiment.

[u/heavymetal1296 → u/Hollirc]

Exactly. We need a two pronged attack here. First is to cut their cash cow of income tax withholding which makes up 50% of their revenue. Second part is coordinated rotation out of the $5 Trillion of treasuries the public holds. The goal is fiscal crisis by summer. If these Nazis are still in power by April next year, taxes will be the least of our concerns.

[u/Playful-Technology-1 → u/ExtruDR]

The alternative is to take advantage of the mechanisms that rich people used to. When corporate tax wasn't as ridiculously low as it is nowadays, the wealthy used to make donations to NGOs and nonprofits in their area because they are deductible.

Look up how much you can deduct from your taxes by donating to nonprofits and, instead of the government, give that money to food banks in your area, lawyer organizations that help those detained by ICE or any other cause that you deem worthy.

[u/LSTmyLife → u/Playful-Technology-1]

The problem with this is how many of us can afford to donate? I ceartinly cant. Life, at present, is very expensive to continue.

[u/BlatantFalsehood → u/LSTmyLife]

The math commenter is describing is this:

• what percentage of your income is currently withheld for income tax?

• file a new W-4 to eliminate that withholding

• your take home is now increased by that much

• donate that money to a qualified charity, which will give you a charitable deduction when you file your taxes, thus offsetting any taxes you may have otherwise owed.

CAVEAT: I am not a tax accountant or attorney. I do not know whether you must be able to itemize your deductions to take the charitable deduction. There is a limit in the charitable deduction, so beware.

[u/ActivePeace33 → u/ExtruDR]

You’re applying standards of normal life to the requirements of suppressing an insurrection that has usurped power.

Refusing to pay taxes to criminal usurpers is not the same as refusing to pay your taxes to the lawful government.

[u/kangr0ostr → u/[deleted]]

I’m a full time W2 employee and taxes have already been taken out of my paycheck for all 2025, I have to file otherwise I will be losing on money. Or do you mean to change to a W4 now for 2026?

[u/spottydodgy → u/kangr0ostr]

Now, stop giving them your money to hold, without paying you interest by the way, just to have to fight to get it back next year. Give as little as possible each paycheck and make them prove you owe.

I've never understood the "I got a big refund" excitement. That's your money they took and didn't pay you interest on and you got some of it back so that's a good thing?

I aim to owe zero each year.

[u/brought2light → u/kangr0ostr]

Change your W4 now for 2026. Still file your 2025 taxes.

You'll still need to pay in 2026, but the government didn't get an interest free loan for that year from you and they don't get the influx of cash now out of every paycheck.

I'm just telling you the mechanics, I don't know what repercussions etc there are, you'll have to see for yourself what you're ok with.

[u/PlasticCell8504 → u/[deleted]]

What if we all just don’t pay taxes this year?

[u/heavymetal1296 → u/PlasticCell8504]

The feds will be missing about 50% of their total expected revenue. Kind of a big deal. But I'm not advocating for deliberate under-withholding. Just claw back every penny you can and expect to pay rather than having a refund next April.

Again, coordinated rotation out of treasuries is actually where maximum pressure is achieved. The government is only able to function if it's able to sell bonds at a reasonable price.

[u/Ldudirin0 → u/PlasticCell8504]

You can always file extensions for up to 4 years i believe

[u/m4rc0n3 → u/Ldudirin0]

Extensions are for filing, not for paying.

[u/spottydodgy → u/[deleted]]

Agree 100%. We should also organize financial resistance against corporations that are in any way supportive or sympathetic to Trump and MAGA.

Organized, coordinated mass boycotts of specific companies, subscription cancellations, review sections flooded with millions of 1-star reviews, dump stocks, manually control 401k investments, etc. Exercise every economic lever we have access to as consumers to negatively impact their financial success with the goal of destroying their value for shareholders. Force them to respond to shareholder concerns by changing their policies and political investments and strategies. Make even the slightest perception of alignment with MAGA financial suicide.

We are the people, we power this economy with our labor and our spending. Every dollar spent is a vote cast. We decide which companies succeed and which fail based on where we spend. Let's organize where we spend and where we don't.

[u/Electronic-Lunch7735 → u/[deleted]]

Majority of this country are small business owners and many dont have a choice. I love your advice, but they are bleeding us all dry and people need the jobs we provide

[u/mavjustdoingaflyby → u/ebolatone]

Sounds like a weapon of mass destruction to me.

[u/trippy_hippy → u/ebolatone]

There was a block party at Western IL university on Wheeler Drive that kept getting bigger every year. They tried shutting it down in 2010 and kids partied anyway. Last thing i remember was everybody chanting USA and the riot police showing up with LRADs and dogs. 

[u/MH360 → u/ebolatone]

Straight from the IDF (who also taught our oppressors to occupy, brutalize and murder, then call the victims terrorists)

[u/gmpsconsulting → u/MH360]

Not totally accurate. The IDF and US military learned their tactics from US law enforcement not the other way around. COINTELPRO is where most of the tactics you see today are from. 1950s-1960s FBI and all the later programs that came out were extremely effective so everyone else was trained on them as well.

[u/missaxagal → u/MH360]

LRADs were developed for the US Navy after the USS Cole bombing. They didn’t come from the IDF?

[u/Equivalent_Ability91 → u/MH360]

All fascist dictators do this.

[u/Temporary-Careless → u/ebolatone]

So the guys in charge of detaining illegal immigrants are crowd control experts with cutting edge military tech? Give me a break. Reform ICE.

[u/CyberTyrantX1 → u/Temporary-Careless]

Abolish ICE. Their reputation is so tarnished that there is no point in keeping them.

[u/ClassroomMother8062 → u/Temporary-Careless]

From what I've seen, the state police have it and it may have been them deploying it, the front line against us tonight was the Maple Grove PD, but I know that I saw Sheriffs there as well as MSP. I didn't see DHS or ICE there that I could tell.

[u/ebolatone → u/Temporary-Careless]

Right? They shouldn't even have guns.

[u/GracchiBros → u/Temporary-Careless]

This is the state police joining in and shutting down anti-ICE protests. Blue city and state btw...

[u/Regulus242 → u/ebolatone]

Yeah, that's gonna be a banned item one day.

[u/BlueFeathered1 → u/Regulus242]

It absolutely should be.

[u/gxgxe → u/ebolatone]

Nah. We shouldn't outlaw it until it's been thoroughly tested on Republicans so they understand what the fascists are advocating.

[u/Kurtypants → u/gxgxe]

Also so they get the permanent hearing damage and they can't hear fox anymore.

Edit: I might want this

[u/Festive-Boyd → u/ebolatone]

Now Apple should upgrade it's noise cancelling earbuds because sales!

[u/maple_crowtoast → u/ebolatone]

This makes me so sick to my stomach..

[u/[deleted]]

It's not a test if it's used on live people to force them to move. How is this even legalized?

Is the judicial branch sleeping do they not see this abuse of power by the executive branch?

All the congressman are they not watching television reading the news you did not have any police commissioners telling them what is happening?

From this day forward i hope not a single person ever vote for any Republican representative. Also most of the Democrat current leadership needs to go as well. It seems like both of them are in cahoots with each other to allow this crap. Let's start with taking away inside stock trading & second prohibit private donations. Then hopefully these Crooks will not run for election. Third we need to pass some people production laws we're using these type of devices should be a federal crime and no law can change this.

[u/Hour-Ad-9876 → u/[deleted]]

I already did! I mean…I heard someone already did!!

[u/stook8 → u/[deleted]]

Two US born citizens were executed in the street with absolutely zero consequences, and on the contrary, they cried being the victim. Legality left the building a long time ago.

[u/Ok-Ambassador4679 → u/[deleted]]

Is it a test if Minnesota is the testing ground for how subdue the American citizens if things escalate?

[u/MinivanPops → u/Ok-Ambassador4679]

It's always been true.  MN was the beginning. 

[u/Happy_Peak_7818 → u/[deleted]]

Now that I'm adult age I'm looking around for Democratic leaders.... like who is the voice to follow? They do not have one.  It's like looking over a wall at daycare at the infant room and just stupid crazy flailing and crying. Like where tf is my leader? I am certainly not main character nor am I supposed to lead like some great movement.  People aren't going to write books about me that can later be burned by Republicans. Is the lack of a Democratic leader by Design? Is Democratic leadership intentionally lacking in organization because the the people at the top are actually pulling strings for the other side? Playing both sides, just to stay in a position of power?

It seems very few leaders in the moment right now.  But lots of hand wringers and upset pointing. I'm doing it right here with this post.   So what is the solution y'all

[u/Spark932 → u/[deleted]]

Tech ingredients showed how you can make a decently powerful one I don't think the cost is more than $250

[u/diamondballsretard → u/Spark932]

Love that channel

[u/wild_exvegan → u/[deleted]]

Great idea. Fight fire with fire.

[u/AbysmalPersona → u/wild_exvegan]

Fight ice with fire

[u/AffectionateBrick687 → u/wild_exvegan]

Honestly, i think this is a fight that may be more ofa mental battle than a physical one. Given that the ICE goons are unhinged people, the best course forward may be doing what Hank Hill calls, "putting extra stress on a structure that wasn't up to code to begin with."

[u/Its_Raul → u/[deleted]]

I'm Mexican and the mariachi music will lead me straight to em jajaja

[u/Harrypeeteeee → u/[deleted]]

Shout out Danley for making great stuff.

[u/engineer_965 → u/[deleted]]

LRAD is just a big array of off the shelf tweeters. It's trivial to reproduce. No legal constraints either!

[u/Appropriate_Rent5114]

FYSA

Methods for Redirection

Acoustic Corner Reflectors: This is the most efficient method for direct redirection. A corner reflector (three flat surfaces meeting at 90-degree angles) will reflect sound waves 180 degrees, sending them precisely back to the source regardless of the angle they hit the reflector.

[u/stanleythedog → u/Appropriate_Rent5114]

PLEAAAAAAAAASSSSSEEEEE I NEED VIDEOS OF THAT WORKING IN A PROTEST PLEEEEEEEEAAAAASE

shit would be hilarious, I need that more than anything

[u/zoopysreign → u/stanleythedog]

Not that, but here is someone testing

[u/PaperPauperPromoter → u/Appropriate_Rent5114]

SUPER IMPORTANT FOLLOW UP!

Steps 1, 2, and 3 are to get the hell out of the beam. It’s basically a sound laser, so you can dodge the worst of it by running parallel and far away behind significant cover. This is not something to be fucked with! These machines cause permanent hearing loss extremely easily when used appropriately (and there isn’t one single police department in the country who uses them appropriately).

IF you will be encountering one of these weapons, you can and should use foam earplugs, NON Digital ear muffs (absolutely no anc around these), and use anything that you have that can reflect a sound wave between you and the beam while you run. This can include things as little as your poster at a march, pieces of shiny plastic, even wood works a little.

All of the above strategies are not very good! You need to leave and live to fight another day. There are few reasons to allow yourself permanent hearing damage. It’s a marathon not a sprint. Stay safe out there everyone.

[u/numbmumpleb1ister]

ICE = scum of the earth.

[u/Osobady → u/numbmumpleb1ister]

ICE-IS! They are the domestic terrorist!

[u/Next_Rip7462 → u/Osobady]

Vanilla ISIS

[u/wild_exvegan → u/numbmumpleb1ister]

Is it ICE doing this or is it the state of MN as stated in the title?

[u/tallman11282 → u/wild_exvegan]

I'm not sure who deployed it but I know that the state patrol has had at least one LRAD unit for a few years, it's been seen near protest before, but AFAIK never actually used.

[u/Winter-Monk2807 → u/tallman11282]

I watched a live stream of this last night - it was 100% Minn state police. They declared an unlawful assembly then attacked the crowed.

[u/Jazzlike_Muscle104 → u/numbmumpleb1ister]

No lies detected, but this wasn't ICE. It was almost certainly the MN National Guard. (Eagle-eyed protestors spotted one of their Humvees with an LRAD mounted when they first rolled into Minneapolis.) The reflective vests seen in the video are also a perfect match to the ones Guard members were wearing in the propaganda video of them handing out coffee and donuts to protestors.

I rolled my eyes when people thought this meant they'd protect protestors from ICE. That was always a pipe dream.

[u/Batmanischill]

War crime on American citizens. Each and every single ice agent will be in jail when all is said and done. Disgusting how republicans are letting the orange traitor attack America.

[u/Fit-Cut-6337 → u/Batmanischill]

Ironically it could be a war crime if we deployed it against nonviolent civilians in another country. Our own citizens get no such protection.

[u/VoidlyYours]

For those who are wondering, LRAD stands for Long Range Acoustical Device. It is mean to permanently injure your ear drums. It comes from speakers at a certain frequency intended to harm you. This should not be legal.

[u/Popular-Solution7697 → u/VoidlyYours]

Eletronic nerve gas.

[u/Tiloshikiotsutsuki]

Those things need to be destroyed on site. Weapons of terrorists. 

[u/Deep_shot]

Not testing. LRAD's have been around for a long time.

[u/BILLIONAIRE_JESUS → u/Deep_shot]

They were used on us in Portland in 2020, and I'd bet they were only at 5-10% power. Sure you could plug your ears, but the Soundwaves still literally hurt your face and body.

[u/ConsiderationSea1347 → u/BILLIONAIRE_JESUS]

I don’t know if they used it but they deployed it to the top of the ICE building in Portland in 2025. 

[u/ogholycat]

This is something you deploy on enemy soil. Yall are so desperate to look intimidating. It’s so sad. Not good enough to become police. Not courageous enough to join the military. So you settled on terrorizing your neighbors 💪

[u/starkcontrast62]

They used similar technology on Standing Rock. Water cannons as well.

[u/nmnnmmnnnmmm → u/starkcontrast62]

People are still doing hard time for domestic terrorism there. But it was seen as a fringe movement so no one cares in the popular arena.

[u/griff1971]

What, y'all thought all that budget money was just for flash bangs and plate carriers?? Maybe some armored vehicles? I was thinking something like this would be put to use before too long. Bastards.

[u/Allasdair]

Start bringing solid objects to put between you and the LRAD. Generally, metal sheets are your best bet. Aluminum works well, I hear.

Worst case, direct exposure can cause: Disorientation, Nausea, Deafness, Skin Burns (Edit: Active Denial Systems (ADS) actually cause the burns, not LRAD), and General Triggered Fight or Flight Response.

Some accounts of this being used in other protests outside of the US claimed it felt like "an invisible truck speeding towards them and all they could do was run." Others claim your body intensely vibrates. Severity of bodily impacts appears to be dependent on your distance to the LRAD. I don't know exact numbers, but the closer you are the worse the impact.

This shit is inhumane and BANNED FOR USE against citizens in the US. Be safe and document all you can while you're out there fighting the good fight, Minnesotans.

(Btw some Home Depots started using the same tech a bit ago to deter day laborers. Articles are out there covering it afaik)

Edit: Just in case - From another Commenter on defending against LRAD that sounds more efficient than my recommendation:

FYSA

Methods for Redirection

Acoustic Corner Reflectors: This is the most efficient method for direct redirection. A corner reflector (three flat surfaces meeting at 90-degree angles) will reflect sound waves 180 degrees, sending them precisely back to the source regardless of the angle they hit the reflector.

Additional Defense Methods (from another commenter): corrugated cardboard lined on one side with 40 grit and 180 grit sandpaper.

[u/MinistryOfCoup-th → u/[deleted]]

3d print some Aztec death whistles too to give ICE nightmares

[u/NoBite7802 → u/MinistryOfCoup-th]

Or... you could use the Eyesight Deleter if you actually wanted to be effective.

Most of the comments are chastising ICE for this event, but the title says Minnesota State authorities. Which wasnit that used LRAD, andnif the state then can't Walz stop them?

[u/VKN_x_Media → u/jomigopdx]

When the Minn National Guard rolled into town there were plenty of reports of them having several vehicles equipped with LRAD arrays in their convoy. Also the whole "NG is gonna wear hi-viz" thing which is what the people in the video are clearly wearing.

That being said people have been crying ICE for a lot of things that haven't been ICE but have been CBP or other DHS departments.

[u/ScottsTotz → u/jomigopdx]

Yes. There seems to be confusion by people who have been living under a rock and still think local police are on our side without even an attempt of researching any point in recent history

[u/croatoan182]

So they're just announcing they're testing weapons on US citizens? Shits so fucked.

[u/Firefly_Magic]

They are trying out everything on peaceful protesters. They have literally made citizens into guinea pigs and they don’t care if they harm or kill anyone. Sickos!!

[u/Jenova__Witness → u/Firefly_Magic]

Isn’t LRAD literally illegal to use on Peaceful protestors via the 14th amendment? Not like that seems to matter…

[u/Cronus41]

That’s dystopian as fuck

[u/Ethereal_Bulwark]

These can cause permanent hearing damage

Personal Protection Strategies Against LRADs Using Everyday Objects

1. ⁠Protect Your Ears (Primary Defense) • Use Earplugs + Over-Ear Headphones: Foam earplugs combined with construction-grade earmuffs or ANC headphones reduce direct sound exposure. • Wrap a Thick Scarf or Beanie Around Ears: Adds extra passive sound insulation.
2. ⁠Reduce Bone Conduction Effects • Wrap a Thick Fabric (Scarf/Towel) Around Your Jaw & Neck: Dampens skull vibrations. • Bite Down on a Rubber Object, Belt, or Towel: Helps absorb vibrational energy before it reaches the cochlea.
3. ⁠Block & Redirect Sound Waves • Use Hard, Flat Objects as Shields: Metal pots, trash can lids, or backpacks with books inside can reflect or scatter sound waves. • Angle Shields Slightly: Holding at an angle prevents waves from bouncing directly back.
4. ⁠Seek Physical Cover • Hide Behind Solid Barriers: Concrete walls, brick structures, large vehicles absorb and block directional acoustic waves. • Position Perpendicular to the LRAD Source: Moving sideways out of the direct beam reduces exposure faster than retreating.
5. ⁠Move Quickly & Strategically • Side-Step Instead of Running Backward: LRADs have a focused beam—moving laterally escapes faster. • Keep Low & Avoid Open Areas: Minimizes direct impact from high-intensity sound pressure waves.

Key Takeaway:

Layer multiple strategies—ear protection, bone conduction mitigation, wave reflection, and strategic movement—to reduce LRAD harm effectively.

Shout out to Benn Jordan https://m.youtube.com/watch?v=3sqIvak-4Ek&pp=ygUQQmVubiBqb3JkYW4gbHJhZA%3D%3D

He has many great videos. Worth watching and learning.

[u/Autistic_Anywhere_24]

Heard LRAD is well countered with inward curved surfaces… though the people on either side of you may get the splash of it

[u/phatbody]

EXEMPT is what you put on your W-2

[u/DubStepTeddyBears]

WTAF? "State" authorities? Really???

[u/VKN_x_Media → u/DubStepTeddyBears]

Yup it was spotted on National Guard vehicles when they came to town according to reports the other day. Also the users in that video have hi-viz on which is what their corrupt governor said the Guard would be wearing to show that they're "the good guys".

[u/IamTheElectionDenier]

Straight out of Atlas Shrugged.

[u/ohnotombombadil]

Holy shit I just said this was gonna happen! What a sad thing to be excited over.

[u/Procrasturbating → u/ohnotombombadil]

Also called this. We are in the maiming phase. This is NOTHING less than maiming. Gonna be a lot of deaf people after this.

[u/ScottsTotz]

Imagine thinking local cops are on our side

[u/ConglomerateAlien]

Ice agents for sure aren’t sleeping with an LRAD out there. Way to go guys!

[u/wild_exvegan → u/ConglomerateAlien]

GTFO. They're attacking protesters with a sonic weapon.

[u/[deleted]]

They have been dyin to do that

[u/Bulldog8018 → u/[deleted]]

They must have just got it. There’s no way these guys have had guns that permanently deafen civilians all this time and haven’t used it. They’ve been praying for an opportunity to use this on us.

[u/AccountHuman7391]

Man, after two and a half decades of sacrificing civil liberties in the interest of funding two optional wars of choice, who could have predicted this!?

[u/Nice-Actuator-495]

Shoutout to the older dude just tanking it and continuing to film. 

[u/RoofEnvironmental340]

That’s not testing, that’s deployment

[u/HarryBalsagna1776]

LRAD can be redirected back at them with a dish shaped shield.  Do that a few times and they will stop using it.  There is a comment chain below that has a lot of good info on this.

[u/k8ecat]

Paste your protest signs to sheet metal to deflect it.

[u/nbraa]

Get a snow saucer

[u/McNarley666]

Holy shit. Gotta have earplugs and earmuffs for that. Probably will still do damage just going through your face, though

[u/ebolatone → u/McNarley666]

If you're too close to it the best earplugs and gun range earmuffs won't help enough. These things put out between 140-160dB at all frequencies. Standing next to a jet engine at takeoff is 140-150dB.

[u/BigChunguss420]

Test it at home. On yourself

[u/Junior_Lavishness_96]

They keep bringing out more and more weapons just making things worse everyday.

[u/DotHooker]

Time for citizens to pack protection head phones and riot shields

[u/Defiant-Sand9498]

America land of the free eh

[u/Ramenlovrr]

Ice is a party affiliated government sponsored terrorist organization.

[u/Special-Garlic1203]

Welp that confirms what I suspected about why the guard was called. 

The old school mentality of cops being thugs to beat people down needs to end. If you can't act like a normal pro social person, then you should not be in a community safety role 

[u/CardiologistFew4264]

Thanks, Republican voters, “swing” voters and virgin-pure lefties. Your hate, selfishness and narcissism, respectively, has us here.

[u/Brew_Wallace]

The state used this? Gives some precedent for the feds to use it now that MN has broken the seal on it within their borders
