Shocking moment a Tennessee police officer choked an unresisting college student until he fell UNCONSCIOUS

A photographer has captured a police officer using what looks like excessive and unnecessary force on a college student.
The sequence of photographs shows the young man complying with police as they lead him to a paddy wagon at the University of Tennessee, before an officer uses two hands to choke him until he is unconscious. The young man was arrested during a wild college party celebrating after a week of finals that spilled out on to the street.Culled
