School Cop Caught Slamming 12-Year-Old Girl To The Ground [GRAPHIC VIDEO]

I am not going to lie, this video is tough to watch! A San Antonio school cop is in hot water after he slammed a 12-year-old student to the ground. Joshua Kehm slammed Janissa Valdez so hard, it knocked her unconscious.

Kehm has since been suspended while the school district investigates. According to one report, the officer told the girls mother that he 'did what he had to do at the moment.' WTF? What could she have been doing that required that type of a slam? Whatever was going on, has not been revealed.
