It looks like something out of a video game, but this monstrous machine could come in very handy for breaking up prison fights.
The Assault Intervention Device (AID) emits an invisible laser-like beam to trigger a brief but painful burning sensation and has been touted as a new type of Taser gun.
Officials plan to set up the machine in a detention centre dormitory in Castaic, California, although it has not yet been given the green light by its federal sponsor.
