When the police supervisor arrives former officer tells his side. Tried to drag the taser and I went off.

Today in court Chris Hickman got to feel what it's like on the other end of the law, mug shot included after resigning in January facing strangulation and two felonies assault inflicting serious issues and communicating threats. Why it took six months to file charges has caused outrage. When they failed to acknowledge something bad has happened only makes us trust them less and make crime increase across the board.

After watching the video behind closed door the district attorney moved to drop charges against rush but not until five months after the incident that criminal investigation fighted against Hickman.
