dreaming of portable pain guns for as long as we can remember, and if it has its druthers, said fantasy could soon become a reality. The Thermal Laser System (or the IR-Lesslethal device, if you prefer) has been brewing since at least 2005, but just recently the weapon prove to testers that it could create a beam strong enough to cause alarm and pain without actually damaging the skin or retina. Think of it as a portable crowd controller (or your worst nightmare, either one). Of course, there's still quite a bit of testing to get through before it's actually rolled out for military or police use, and there's the fact that leaving no marks leaves open the possibility for undocumentable abuse. Not like that would ever happen, though.
