Texas Cop Body Slams Twelve-Year-Old Into the Ground [VIDEO]

All I am saying is, was that really necessary? 

Some pretty disturbing video out of San Antonio shows an officer using what many are calling excessive force on a twelve-year-old. The officer was called to the school to break up a fight that was going on. The officer is Joshua Kehm who has been put on paid leave and the department is currently investigating the incident.

Many people are saying don't get in the fight and this wouldn't happen. Which I agree with. Was the body slam necessary, though? The girl looks like her head hit the ground so hard she was knocked out.
