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."

    This is not a new concept. I recall hearing about this class of device twenty years ago when I worked the door at a couple of bars - always wished I had one (it's a hard way to make cash to fund your education, letting people beat on your head so you can learn to make a living with self-same head). Never saw one though.

    Here's a reference from 2005 to such a device, with a different name. I don't know if it is the same company, or a different development: http://www.defense-update.com/products/s/sabershot .htm

    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!

    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.

    Nothing like taking a single isolated incident - which occured just weeks after four suicide bombers killed 52 and injured 700, and days after another four tried but failed to repeat the attack, and in which the officers concerned were told that they were tracking a known terrorist suspected (and later confirmed) as being part of the threat - and blowing it out of proportion.

    Jean Charles de Menezes died because many things wen't wrong that shouldn't have been allowed to go wrong. And while I'm not excusing either the commanding officers that misinformed their subordinates in the field, or the officers that delivered the killing shots themselves, it's unreasonable to suggest that this single isolated incident is a typical police response.

    Nor, not that it needs to be said, has anybody attempted to defend what happened with a "reasonable force" defence.

    If you're going to use an example then at least use one that's typical rather than one that's unique, or at least put the example in context and provide the reader with some facts rather than sensationalism for sensationalism's sake.

    Did de Menezes die as a result of a police overreaction? Yes. Was it in any way a normal reaction to a normal incident? No.

    For those that would prefer some facts: Wikipedia article on Jean Charles de Menezes.

    The Geneva convention refers also to the rights of the "prisoners of war". A prisoner of war is an uniformed soldier, captured while fighting for its country.
          The freedom fighters from Iraq, or the ones from Afghanistan, or others, are not technically protected by those regulations - they are not uniformed, and they are not fighting for their country (the government recognized at the international level).

          So, the Geneva convention is not perfect

    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".
