California’s Pitchess Detention Center will be using Raytheon’s Assault Intervention Device (the Pain Ray). This device is designed to focus a ray of invisible energy rays at misbehaving inmates that will cause a gentle sensation of searing flesh. The device does no damage, but its ray penetrates the skin about 1/64th of an inch over an area about the size of a CD. The pain stops when the target gets out of the way of the beam.

The Pain Ray is still in its experimental phase, but if it works, it could become a jail staple.
