In April of 2010, five police officers put Michael Kingsley face down on a cement bunk in a holding cell, shocked him with a stun gun for five seconds, then left him alone, writhing in pain with his hands cuffed behind his back, for 15 minutes. Kingsley sued the officers, claiming they violated his constitutional rights by using excessive force. He lost.
