The ultimate gizmo to repel an attack isn't one that can destroy the opponent but rather make him immobile yet be left alive. For riots and chaotic situations, police often use tasers, rubber bullets and pepper spray to try and control the crowd. But there could soon be a new weapon in their arsenal: a hi-tech flashlight with a big punch. Nausea and a feeling of disorientation soon follow. The device is called the "LED Incapacitator." Intelligent Optical Systems is the company building it right here in California, thanks to an $800,000 contract from Homeland Security. Once Lieberman turned on the Incapacitator for us, we started feeling the effects. The device flashes LED lights at several specific frequencies. Before your brain has time to adjust to one frequency, the Incapacitator flashes another. Add multiple colors and random pulses and the brain just can't keep up. The longer you look at this, the more you don't want to look at it, the only ways to escape the effects? Close your eyes put your hand up, turn your head away, all of which will give the user the advantage they need and which is the only point to the whole device. That's news to Homeland Security. The department says it may be restricted to just law enforcement. Still, by 2010, Intelligent Optical Systems hopes to be selling this technology on store shelves.

The whole point of this weapon is to disorient you, and it does. Some are concerned that if the public will get its hands on this, means criminals will too.
