Homeland Security Funds LED Light That Blinds, Disorients

katzmeow writes "Ryand Singel's Wired blog notes that Homeland security has developed an LED flashlight that uses 'powerful flashes of light to temporarily blind, disorient and incapacitate people.' The idea is to use it to incapacitate people — 'arrest them' — on airlines, borders, etc. without using traditional weapons. The company's president Bob Lieberman says the tool is perfect for confronting 'border jumpers.' 'You don't want to hurt or kill them, just take them into custody,' says Lieberman. 'With this, they don't need to know English to comply.' The 'light saber' can even be scaled up to bazooka size for subduing crowds."

Re:I'm sure...

[jollyreaper]

Why is it that the introduction of a non-lethal, safer-than-shooting-a-gun method of subduing a suspected criminal considered such a bad thing? If I were as paranoid of the government as you obviously are, I'd rather have them weilding a temporarily blinding light than to just save batteries and cram a load of C4 up my rear. Seriously, what's up with you people? The problem with less-than-lethals is that they were designed with the idea of "at least now there's an option other than shooting someone." That's fair. But the way they're used is "I don't feel like wrestling you to the ground and cuffing you, have some taser." The assumption is because it's called non-lethal (although it should be called less-than-lethal, most of the time) is that the cops don't think there's any risk associated with it. You're not as likely to kill someone with a taser than a gun, but you're still running more of a risk than if you subdued them the old-fashioned way.

I think the operating rule with these less-than-lethals should be "If you didn't have one of these and you would otherwise be shooting them with a gun, that's when you use these. If you would never have resorted to the gun, stick with the nightstick."

Right! They'll never suspect a thing if i walk into the airport with welder goggles on. Never i say!

Re:Easily countered

[juhaz]

Ordinary sunglasses will probably be enough to render this thing useless, and they're rather less, um, conspicuous than welder's goggles.

Nice

"subduing crowds"...I don't like the sound of that.

Re:Nice

[CmdrGravy]

I like the fact that it can be used for subduing crowds without having to talk to them, everythings much simpler when you don't have to engage in any dialouge with enemy.

Re:Nice

[badfish99]

I wouldn't like to be subdued by any of them, thank you very much.

But, if you're going to give the police a weapon, there's an argument that a gun is better than any of these. Everyone knows that a gun is lethal, so a policeman is going to think carefully before using it on anyone who is not immediately threatening his life.
But if the policeman has got a simple non-lethal weapon like this, he's got a strong motivation for "subduing" anyone who happens to disagree with him or who doesn't instantly obey his orders. What better instrument of oppression than a police force that is always instantly obeyed for fear of something like this?

This is against Geneva or Hague convention

[coder111]

As far as I remember, intrenational laws of war forbid using weapons that blind beople.

And this WILL blind people. If used from too far away, it won't be efficient so they'll make it more powerful, then used from close range it will make permanent injuries to the eyes. Similar like tasers aren't supposed to kill people, but they do.

As far as I remember, there was a project in the military to make a similar weapon, using UV laser, but it was scrapped because it was against the international law.

Of course there are precautions that can be used against this weapon, propper googles should do it, but not everyone will have them.

No problem there: The US has not (yet) officially declared war on itself, so using this on US citizens is perfectly fine for the time being.

Re:This is against Geneva or Hague convention

[d3ac0n]

And this WILL blind people.

I'm sorry, but I have to call BS on this one. While I realize that it's oh so fashionable amongst the intelligentsia so make all sorts of wild accusations against the United States as the very incarnation of Cthulu, it just rings hollow here.

First of all, what causes people to go blind while looking at Lasers? well, let's check Wikipedia shall we? http://en.wikipedia.org/wiki/Lasers#Laser_safety

the money quote is here:

At wavelengths which the cornea and the lens can focus well, the coherence and low divergence of laser light means that it can be focused by the eye into an extremely small spot on the retina, resulting in localized burning and permanent damage in seconds or even less time.

(emphasis mine)

The reason lasers can blind is due to the nature of the laser itself, being a highly coherent and concentrated beam of light, which the cornea can further concentrate to dangerous levels. LED's, while very bright, are of a highly INcoherent and diffuse nature. Now, there may be some TEMPORARY blindness caused by the overall light intensity, also known as Flash Blindness ( http://en.wikipedia.org/wiki/Flash_blindness ) but nothing permanently damaging. Also, as someone else mentioned above, there is a range-finder on the thing designed to adjust the intensity based on the range of the target.

So what we have here is a non-lethal weapon designed to harmlessly incapacitate an individual, allowing law enforcement to take them into custody without exchanging gunfire or risking serious injury or loss of life. Frankly, that sounds like three things to me:

a) A good overall idea
b) Something the UN would really go for (why kill when you can humanely capture?)
c) NOT something that an Eeeevil entity would do, unlike the way the US is commonly characterized on /. and other places. (Maybe the US isn't so evil after all?)

Remember, calm logical thinking is your friend, knee-jerk reactions are not.

So what we have here is a non-lethal weapon designed to harmlessly incapacitate an individual, allowing law enforcement to take them into custody without exchanging gunfire or risking serious injury or loss of life. You are completely missing the point. Your last comment completely describes what the Taser is meant to be, but the whole point is that once someone in authority has a means to "subdue" a person with what they think is a method that cannot result in any permanent physical damage, they lose control, and inevitably cause more damage than would have been done with a lethal weapon which has clear and serious consequences. We've seen this with Tasers already.

Picture it, one crowd is protesting with a police force armed with lethal weapons, and non-lethal weapons that leave bruises, the other is protesting with a police force armed with LEDs. The first is not going to fire on a crowd except in self-defense, to do otherwise would be crazy, it would also be a bit difficult to go around and give everyone a bashing. The second is getting impatient and gets out an LED bazooka, and decides to put the brightness up a bit because it's a bright day, oh and they aren't sure if everyone had their eyes open the first time, so they fire it a few times just to be sure.

Or more likely, a middle-eastern looking youth is spotted in a library on a university campus, when asked for his student ID he says he doesn't have it, and won't leave. Someone calls security, security approaches him and tells him to leave. The youth says he won't leave, the security personnel get pissed off and pull out their handy LED weapon, and hold it a centimeter or so from his eye. They repeatedly flash him as he shouts out at them.

As for your claim that a very bright light source with a relatively high divergence from a large distance can not cause permanent damage, I think you need to look directly at the Sun a bit more.

Re:This is against Geneva or Hague convention

[Cyberax]

Just for your reference: I've spent once about 2 months blindfolded after I got by a powerful search floodlight (we were sailing in canoe down the river and accidentally came too close to a military base).

Doctors said that it's a fairly common reaction on very bright light. I was lucky to recover almost completely. Not all are.

Re:This is against Geneva or Hague convention

[mikael]

There was a tactic developed by James Maskelyne towards the end of World War II, that allowed the Suez Canal to be defended against German fighter pilots. He basically took a searchlight and placed a set of tin reflectors on top of the search light, which were then made to rotate rapidly. This had the effect of creating rotating cartwheels of dark and bright patches of light in the area around the searchlight. Any pilot who flew above this area would become disorientated due to the mismatch between the perceived motion from the brains centres of balance and the visual cues seen through the aircraft windscreen (optic flow).

I would guess that this portable system creates enough glare in the eye to make moving bands of light appear on the retina. With a wide enough beam, this will disorientate an entire crowd.

Re:This is against Geneva or Hague convention

[yani]

See how it works now? Some police are good, some are bad, and you can generally tell which are which by the societies they live in. I wish I lived in your world. In the real one there is no such distinction and psychology tells us that in a position of authority often the worst comes out in even the best people, the Stanford prison experiment (http://en.wikipedia.org/wiki/Stanford_prison_expe riment) is one of the more famous examples of this.

Oh, and let's not get into the differences between THE SUN, a gigantic nuclear blast-furnace bright enough to light up the entire damn SOLARSYSTEM and be seen from BILLIONS of miles away, and an LED light about the size of a pea that runs off a AA battery. Just like the "pointing a laser at your eye" argument the OP made, it's an apples and oranges comparison that is neither germane nor logical. It's an extreme example, but your post implies that only a laser can permanently blind, while this is obviously not true.

There really should be a down-mod for "stupid, illogical thinking" I think it would apply well to your post.
What a logical and clever thought. Thanks.

Re:Vlad calls it the evil color

"There's one wavelength that gets everybody," Lieberman said, according to the newsletter. "Vlad calls it the evil color."

And if the psychophysical effects are limited to a single or range of wavelengths, these effects are easily blocked with Dichroic Filter Sunglasses. Or better yet, Peril Sensitive Sunglasses.

The good news if the DOD is again looking for creative ways of wasting money, this obviously means they are nearly finished with the cleanup from two wars. Couple hundred billion here, couple hundred billion there and pretty soon you're talking about real money!

Epilepsy warning?

[ParaShoot]

The LED Incapacitator uses a range-finder to measure the distance to a target's eyes and then unleashes continually changing, multi-color light pulses that both blind and disorient the person. How long until this triggers an epileptic seizure in some poor unfortunate - and worse still, would whoever's wielding it be able to tell the difference between the potentially life-threatening seizure and the normal reaction?

How to deal with Johnny Foreigner

[fantomas]

"With this, they don't need to know English to comply"

My word sir, you Yankees are becoming more like the true heirs to the British Empire as every day passes! Well said sir, Johnny Foreigner is a semi-savage, and can't speak a word of the King's English (or President, or whatever you colonists have these days). Don't be fooled by his suit, you'll find it's a cheap imitation and close examination will prove that the buttons on the cuffs are fake and the pockets have been cut at the wrong angle. Shine a torch in their faces, and shout in God's own language NICE and LOUD and SLOWLY. They'll understand then, by George!

Re:No guarantee of safety when breaking the law

[arth1]

Yes, but "reasonable force" is a fluid term. In the UK, it apparently means shooting an unarmed guy, then when he's on the floor, step on his arms and shoot him in the head, over and over again.
A better term would, in my opinion, be "minimal force". At least that doesn't expect police men to be reasoning beings.

LEDs count as Laser's now too

[Cassini2]

I think you are missing the point that the laser safety regulations are busily being modified to include LED light sources. LED's, while non-coherent, can be focused sufficiently to create similar effects. It is all about how much light energy is hitting a person's retina. The effect can be created with any light source of sufficient intensity. Both a very bright focused LED and a laser can (temporarily) blind people.

Re:No guarantee of safety when breaking the law

[soren100]

Jean Charles de Menezes died because many things wen't wrong that shouldn't have been allowed to go wrong. No, he died because police officers jumped on top of him and fired 7 bulllets into his head. Then they lied about the details to make the actions seem much more reasonable. The only reason that the horrifying truth came out was because outraged individuals risked their jobs and their freedom to make the truth known. The police still claim that the multiple CCTV cameras covering the incident were all malfunctioning at the time.

If you're going to use an example then at least use one that's typical rather than one that's unique. Unfortunately police brutality and consequent coverups to avoid the consequences of the brutality is unfortunately very typical. Each case is unique, but the overall pattern is far too predictable.

The gunning down of a 92-year-old grandmother in a botched drug raid was also a unique case, and so were the accompanying lies attempting to justify the actions and make them seem reasonable.

Here's a map of the details of all the "unique" botched paramilitary raids in America.

The original claim stands true. "Reasonable force" is a fluid term, and far too many innocent people die from police mis-application of "reasonable force".
