Prison Pain Rays

Prisons will soon be implementing the pain ray to keep unruly inmates in line.
Its laser uses a focused beam of heat to penetrate the skin the equivalent of 3 sheets of paper,
to cause an intolerable burning sensation.
The pain ray was first introduced in Afghanistan to counter terrorism in a "peaceful" manner,
but has more recently hit the shores of America to control crowds.
The technology will soon be tested in American prisons and if successful will surely be a permanent mainstay.
Non-lethal weapon development is all the rage nowadays.
