StunRay Incapacitates With a Flash of Light
Hugh Pickens writes "Scientific American reports that a newly patented method of non-lethal incapacitation can render an assailant helpless for several minutes by overloading the neural networks connected to the retina with a brief flash of high-intensity light. 'It's the inverse of blindness—the technical term is a loss of contrast sensitivity,' says Todd Eisenberg, the engineer who invented the device. The device consists of a 75-watt lamp, combined with optics that collect and focus the visible light into a targeted beam, which can be aimed like a flashlight to project a controlled beam of white light more than 10 times more intense than an aircraft landing light with a range as far away as 150 feet. Recovery time ranges from 'seconds to 20 minutes,' says Eisenberg. 'It's very analogous to walking from a very bright room into a very dark room.'"
...and I'm sure the long term effects of overloading your sensitive, incredibly difficult and costly to regrow optic nerves to this degree are well known, and this represents no long term danger. right?
The issue with tasers is not that they exist, but that they are misused -- Taser International has misled police and the public to believe that tasers are more safe than they really are, so police will happily overuse them without making as many judgement calls as if they used live weapons. While trying to ban tasers is misguided, trying to educate people about them (especially when people with financial stakes try as hard as they can to obscure the information) is not.
