Ft Worth police officer in the city jail slams a hand cuffed man's head into a wall and then slams his head into the concrete floor. And if that is not enough, I counted at least 5 additional police officers just standing around watching. This prisoner is laying on the floor bleeding from his head and no officers appeared to call for medical assistance. These six police officers should be fired immediately and locked up in cages for awhile. Other officers were coming and going in this hallway and they had to walk around this individual and did not stop to assist the injured man.
