The FBI has launched a criminal probe into a January incident where Tennessee police stripped a man naked, then kicked and beat him while he lay handcuffed in the snow.
The incident, recorded by a patrol car's dashboard camera, also reveals police repeatedly shocking the man, Darrin T. Ring, of New Johnsonville, Tenn., with a Taser and spraying him with pepper spray.
For nearly ten minutes, the video shows Ring writhing and screaming in pain as a gaggle of officers shout contradictory demands at him.
"If he even flinches, shoot his ass," one officer declares on the tape.
