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."
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.
Have you seen this?
We're napalming civilians, now.
Not to sound condescending to the younger slashdotters amoung us, but this isn't in fact, as recent a development as you might think. There was this thing way back when called The Vietnam War, where US forces used napalm quite copiously on civilians.
History inevitably repeats.
May the Maths Be with you!
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:
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
