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.

    From TFA " But the device will require close scrutiny to ensure compliance with a United Nations protocol on blinding laser weapons." "Laser weapons capable of blinding enemies have been developed in the past but were banned under a 1995 UN convention called the Protocol on Blinding Laser Weapons. The wording of this protocol, however, does not prohibit lasers that temporarily dazzle a foe."

    I love acronyms that are stretched to fit a word. "Stimulation response"? It sounds like they're tickling a target's balls or something.

    All this military spending in name of "national security"....meh I couldn't care less about national security. The harder it becomes to take over America, the harder it becomes for us to exercise our rights and overthrow our current form of government, should we see fit. I'd rather live my life and chance dying than be dead my whole life without a chance to live as a free man.

    Sure. Situation 1: Driver runs initial checkpoint. Checkpoint team attempts to fill car with bullets before car closes to effective suicide blast range. Situation 2: Driver runs initial checkpoint. Checkpoint team blinds driver. Driver is unable to navigate serpentine blast barriers and crashes. The (notional) probability of somebody dying in situation 2 is less than in situation 1.

    Personnel Halting And Stimulation Response???

    I can see why they made up that acronym though, because RBFTSOLLAF (Really Bright Flashlight That Sort of Looks Like a Fish) is way too long, hard to pronounce, and not as cool.

    Also, is it such a good idea to blind someone driving a moving vehicle. Couldn't that increase the potential for damage somewhat?

    oh yeah, real smart. Anyone who drives through a road block is probably going fast. Mix that in with the fact that you're dealing with a multi ton object. Instant blindness to whomever is driving.. yeah good move If you don't understand that well enough here is another example: A person intent on causing harm is blinded.. he has a gun. Does he A: Sit there like a fool? or B: Spray as much ammo around as possible? Don't make me answer that for you

    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.

  12. Really bad idea. by Kadin2048 · · Score: 5, Insightful

    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.

    A 1995 UN Convention bans the sale of devices which have as one of their purposes, the intent to blind 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
