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.'"

      Only valid on the assumption that a gun would have been used in place of the Taser. Unless you're telling me that the police would shoot someone for refusing to promptly follow an order (while posing no direct threat), that's demonstrably not the case.

      I don't actually object to tasers per se, but I do object to police guidelines which allow their use against people who pose no threat to either the officers or the public around them. Most of the pro-taser arguments revolve around their use as a defensive weapon, but their actual use is not limited strictly to defence. I know such policies would be imperfectly applied, but it would still be better than the current system in which they can be legitimately used as immediate 'punishment' for failing to comply with police commands.

      If tasers were used to prevent someone from harming themselves or others, then I would be AOK with them.

      But they are used as offensive weapons to enforce compliance by most police departments.

      And it is so much less paperwork to fill out if you enforce compliance with a taser, as opposed to if you actually had to beat the fucktard's as with your billy club, ASP or baton.

      I personally have seen an inmate hit with a taser, and then get beat because he refused to lay stils ordered.

      Ignoring the fact that the CO with the taser kept jolting him, which lead to muscle contractions, which lead to four other COs hitting him with 4' long hickory riot batons.

      Bah.

      The problem is that almost every police force in the world uses tasers *improperly*.

      This is because of the lobbying, and the lies, all claiming that tasers are not dangerous. As a result, police do not assume there are risks with tasers. They use them indiscriminately, and in fact, many forces use them instead of physical restraint!

      For example:

      http://en.wikipedia.org/wiki/Robert_Dzieka%C5%84ski_Taser_incident

      Five RCMP officers, and a slightly agitated man... tasered TO DEATH. Hell, one of those officers, with their training, should have been able to 'take down' that man.

      I've seen videos of people with traffic violations, who are perhaps a bit 'lippy' to police, being tasered. Absurd. That is the real issue. That is why the public dislikes tasers.

      Tasers need to be labelled a dangerous weapon. They should only be used when an officer would normally use a gun. I'll say again, the ONLY time a taser should be used, is when an officer would use a handgun instead.

      Because Taser International is extremely litigious, going so far as to sue the government of B.C. for even studying ESW safety. Because Taser makes more money if the weapons are misused, and microeconomics therefore predicts that they will recommend overuse as a rational agent. Because they aggressively market their weapons as a non-lethal* general-purpose alternative and prove it with bait-and-switch like product demonstrations on physically fit, passive police officers.

      There's nothing inherently wrong with tasers, as long as people understand what they are, how they work and how they should be used safely. Taser International is a god-awful company of evil people and their products will continue to be misused as long as they have a say in how they should be.

      http://www.americanrhetoric.com/speeches/dwightdeisenhowerfarewell.html

      here's an excerpt, but the whole thing is extraordinary and prescient and should be mandatory slashdot nerd reading

      Until the latest of our world conflicts, the United States had no armaments industry. American makers of plowshares could, with time and as required, make swords as well. But we can no longer risk emergency improvisation of national defense. We have been compelled to create a permanent armaments industry of vast proportions. Added to this, three and a half million men and women are directly engaged in the defense establishment. We annually spend on military security alone more than the net income of all United States cooperations -- corporations.

      Now this conjunction of an immense military establishment and a large arms industry is new in the American experience. The total influence -- economic, political, even spiritual -- is felt in every city, every Statehouse, every office of the Federal government. We recognize the imperative need for this development. Yet, we must not fail to comprehend its grave implications. Our toil, resources, and livelihood are all involved. So is the very structure of our society.

      In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.

      Akin to, and largely responsible for the sweeping changes in our industrial-military posture, has been the technological revolution during recent decades. In this revolution, research has become central; it also becomes more formalized, complex, and costly. A steadily increasing share is conducted for, by, or at the direction of, the Federal government.

      Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers. The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present -- and is gravely to be regarded.

      eisenhower, on the flip side, was the guy who put "in god we trust" as the motto of the usa and "under god" into the pledge. boooooo. i understand he was a religious guy, but he completely screwed up the whole separation of church and state. like any man, brilliant and some respects, moron in others

So yes, I was most definitely an innocent bystander in the wrong place at the wrong time and AFAIC the police had absolutely no excuse to behave as they did. Furthermore, I was far from the only innocent party wronged by Seattle PD that day.

      Yes, everyone who died during or shortly after being tasered [and generally more than once] were all wusses. With weak hearts, small bladders, and obviously in the middle of a cocaine high.

      Because if it's been established that for most people without a heart condition can take being tasered a single time without lasting affects [which is what Taser International has established].

      Of course, in real life, cops:
      1) have no idea if the person they are tasering has a heart problem
      2) believe if you can tase them once and they don't die, you can tase them as often and as much as you feel like it

      For example, google "vancouver airport taser death" for an example of someone dying because:
      -he was elderly
      -he didn't understand english
      -he didn't comply with instructions in english within 25 seconds [not that he was attacking anybody, he just didn't flop onto the ground immediately]
      -he was tased 2-4 times [police claim they only got him twice, witnesses say 4, including twice after he was cuffed and on the ground]

      Hell, even the "don't tase me bro" guy, who was a dick, got tased multiple times, despite being held face-down on the ground by 4 cops.

      At least there is SOME accountability, in that the device supposedly keeps a record of when it has been triggered, and there is something either physically pressed against you or is shot towards you indicating who fired. I can't wait until they perfect the long-distance heat ray, also a 'compliance' device, which burns your flesh from a significant distance. You can just be wandering around in a crowd, and suddenly your skin [including your eyes] is burning. Not just the sensation, but is actually burning. And you have no idea how or why it is happening. And no way to prove afterwards that any specific individual or group did anything to you [other than yes, you appear to have second degree burns on your face and upper body].

      Good times.

    A laser is very concentrated light, further focused by the eye, which is why it will cause burning damage to the retina.

    This is similar to the flash-bang grenade. A very strong difuse source of light will drain your retina of the signal substance it uses to detect light, and it takes the body considerable time to produce new signal substance. Fire a camera flash in your own face and you can experience a mild form of the effect.
