Set PHASRs On Stun

brianber writes to tell us NewScientist is reporting that the US Government has unveiled a new weapon in their non-lethal arsenal. The Personnel Halting and Stimulation Response (PHASR) laser rifle has many potential applications such as temporarily blinding a suspect who drives through a roadblock. So far, however, the DoD has declined to comment on the specific details of how it works.

      Hard to find anything that's totally non-lethal if you get down to it. A pillow is lethal, if operated in a certian way.

      I think the cutoff is mainly the design of the weapon.

      A gun is designed to kill and thus a lethal weapon. It's not guarenteed to kill, of course, if you miss your target, or hit them in an extremity or an area they are wearing enough armour it won't work. However it is very often lethal and really, that's it's function, at least when fired at a person.

      A taser is designed to incapacitate you and thus a non-lethal weapon. In all likelyhood, you'll be fine after a tasering. Plenty of people are tasered each year, in training as well as the field, and maybe one or two die. Generally it's also a case where it's not clear the taser was at fault. Like guy high on multiple drugs has heart attack. Well sure, maybe the taser did contribute, but I think the "lots of drugs" was a major factor too.

      I guess you can play the semantics game if you like but, generally speaking, when you operate a non-lethal weapon correcly and as intented, nobody dies. When you operate a lethal weapon correctly and as intended, your target dies. PLaying the name-game doesn't really change anything.

Cheney is now working hard behind the scenes to make sure that it dies when in the House or during committee, and Bush has vowed to veto any such bill. The official stance is that such language would "hinder the US's ability to defend itself."

    Given recent news reports of the US using white phosphorus on civilians and napalm when taking Falluja, it's doubtful that Geneva conventions were even considered when this prototype was developed.

      "The Bush Administration has adopted exactly the right posture on the matter. Candor and consistency
      are not always public virtues. Torture is a crime against humanity, but coercion is an issue that is
      rightly handled with a wink, or even a touch of hypocrisy; it should be banned but also quietly
      practiced. Those who protest coercive methods will exaggerate their horrors, which is good: it
      generates a useful climate of fear. It is wise of the President to reiterate U.S. support for international
      agreements banning torture, and it is wise for American interrogators to employ whatever coercive methods
      work. It is also smart not to discuss the matter with anyone.
      If interrogators step over the line from coercion to outright torture, they should be held personally
      responsible. But no interrogator is ever going to be prosecuted for keeping Khalid Sheikh Mohammed

    You're right. The US/NATO are one of the most consistently morally upright military forces during wartime; I have no argument with that. I'm also convinced that if say, China/Russia had invaded, we'd be seeing much more brutality and inhumane treatment stories.

    That's not the problem.

    The problem is that the US declares itself as a "City Upon a Hill," a force for freedom and democracy in the world - a perfectly noble and admirable goal, but one that invites criticism. A country that claims it fights for freedom, democracy, and human rights must hold itself up to the highest standard if it's to maintain moral authority in war. The reason America is criticized so harshly and is watched so closely is that few other countries in the world claim to invade other countries partially on the basis of bringing freedom and equality there. (Whether that was the original intent is irrelevant - the Administration has publicly shifted towards this new rationale). You cannot espouse the rule of law and human rights to other countries if you yourself fail to live up to that standard.

    A leader cannot make excuses for immoral behavior, only rectify the mistakes and never let them occur again.

    The same reason chemical weapons were banned. Contrary to modern scare tactics, chemical weapons are notoriously *ineffective* killers. In WWI (which had the most widespread use of chemical weapons in human history), several tonnes of chemical munitions were produced for every fatality that they caused. What they do, however (in addition to breaking lines), is maim. Societies got back from that war a bunch of people who were damaged and broken. Chemical weapons were initially championed for the same reason US is pushing things like this blinding weaponry - they were supposed to be a more humane way of fighting wars, by making your foe no longer able to be an effective combattant (in fact, chlorine gas accomplished this often through blinding) while not being as likely to take their life. However, after seing people return from the war burned, blinded, etc - many decided that this wasn't more humane at all, and pushed for a ban.

    Naturally, if a person is only temporarily blinded, it's not the same situation. However, there are ample reasons to doubt how "temporary" this will be. Even if they have a laser range finder that adjusts output power, reflection, eyewear, and even things like car windshields can greatly distort the intensity delivered - and even a pulse that causes "temporary blindness" is going to be awfully bad for the retina.

    That's idiotic.

    Go stand in front of a car sometime and try and figure out how you'd like to shoot the tires, especially if it was driving towards you at high speed. They're not exactly a huge target to begin with, plus they'd be turned end-on, and all but the very bottom is covered by the front fender in most vehicles. Now imagine trying to shoot them and only them, using a machine gun, probably mounted on another vehicle (putting it ~6' up in the air) so there's a downward angle, and you'll realize it's highly impractical. Furthermore, it would really suck to waste your last chance at stopping a car by shooting at its tires, only to realize the instant before whatever large amount of explosive that it's carrying detonates, that it had run-flats.

    This whole "shoot the tires" idea is pure Hollywood. If you're putting bullets into a car, chances are the situation has already degraded past the point where non-lethal force is appropriate anyway. Most of the time if you're trying to stop a car, you don't even aim for the driver, you'd be aiming for the engine block, which is unfortunately mounted in front of the driver. Cracking the block pretty much guarantees a quick disable of the vehicle, and is conveniently located "center mass" so it's not difficult to hit.

    Think about the real world practicality of your suggestions in the future. There's a reason soldiers aren't trained to aim for the tires when somebody is trying to ram a roadblock, and it's not because they get a sick thrill out of shooting people.

See http://www.un.org/millennium/law/xxvi-18-19.htm So the whole war vs peace thing isn't really relevant. However, that convention seems easy to get around - if blinding someone is a SIDE effect - it seems like it would be allowed:

    Protocol IV on Blinding Laser Weapons prohibits the use of laser weapons specifically designed, as their sole combat function or as one of their combat functions, to cause permanent blindness to unenhanced vision, that is to the naked eye or to the eye with corrective eyesight devices. The High Contracting Parties shall not transfer such weapons to any State or non-State entity.

    I just happened to be finishing up an excellent, if a little dated, book on Laser Weapons called 'Laser Weapons - The Dawn of a New Military Age' Its out of print, but if you can find it, I highly recommend it. Co-authored by a military Major General and a Biomedical Engineering professor specializing in eye injuries, etc.

    One thing that is NOT in TFA, is this key fact about Low Energy Laser weapons:

    It is not possible to only flash blind a person with a laser for a sufficient time in broad daylight without simultaneously causing permanent changes to his eyes. Temproary flash blinding by a laser is only possible when eyes are more or less adapted to darkness.

    The key point here is that a laser weapon like this will only be 'safe' on the targets at night. During the day it won't work.

    If you really want to poke around and see whats out there, both experimental and deployed, try some of these searches (and since most stuff related to laser weapons is still highly classified, take what you read with a grain of salt):

    These are programs primarily from the late 1980's and 1990's, but it gives you an idea what they were looking at back then and some may still be in R&D today. Systems like Stingray and LDS were deployed at some point or came very close to it.

    One thing most people don't realize is that High Energy Laser weapons (HEL) like proposed for SDI, etc, are VERY difficult to deploy and run into serious problems with atmospheric distortion and interference (lookup Laser Thermal Blooming on Google - its a neat effect) But Low Energy Laser (LEL) weapons can easily blind soldiers, destroy optics, and destory sensitive sensors on vehicles, aircraft, and missles, and aren't as severely impacted by the environment like HEL weapons are. Plus they are CHEAP to build and the technology is widely available - thus the weapons aren't limited to the G-8. If you think terrorists haven't considered using LELs you're kidding yourself. They may not have the dramatic effect - but imagine the psychological impact on a society (think DC Sniper) if numerous people started going blind just walking down the street. Why do you think the FAA freaked out so badly when people pointed handheld laser pointers at landing aircraft. I have a Class IIIa laser on my desk I bought for $50 - how hard would it
