I've been thinking more about this (not in terms of buying one, because for one I don't have money, and two I don't think I'd use it): This could be used in Iraq/Afghanistan/war-in-general. It would be REALLY bad if the Taliban and insurgents got ahold of these. D: I bet you could quickly clear houses with a couple 1W lasers and some helmets with $150+ protective visors. And then snipers ... just imagine the horror they could experience if a soldier shined it in the right direction. (Probably wouldn't even have to try very hard on the part of aiming to get the job done.) Someone could build a minigun with 8+ pipes of 1W lasers. Someone could make a ring that they wear on their body -- or maybe composed or multiple rings. Each ring could have a laser pointing away from the person, and have 8+ 1W lasers. Each ring would rotate in different directions/speeds. Then imagine the potential chaos that could ensue in various places around the world ... like in New York, or Afghanistan, or Africa, or a FIFA World Cup soccer game, or a museum of glass, or a museum/place of jewelry and diamonds, or in prison (if you could manage to sneak one in), or in bathrooms of mirror-frenzy, or a swimming pool/center, or against a riot, or against anti-riot/SWAT (of course you could expect being shot at, but if you aimed carefully and had some luck on your side...), or in places like Korea/China when there are protests, or one of those nudist people that run out onto the field during a soccer game could use one of these 1W lasers to prolong their attention, or use in a [high-speed?] pursuit, or ... Someone could even mod one of these onto a paintball sentry turret and have it activate the laser when it sights and engages at a target.
