Two police officers in St. Petersburg, Florida, arrested a homeless man for trespassing. The female officer who arrested him told him she was tired of citing him, so she was going to have him taken for a “ride” in the police van. He was shackled and placed in the rear of the van, that had no seatbelts. Along the way, the officer driving the van slammed on the brakes, rendering the detainee unconscious. But the officer didn’t stop. Later the officer opened the rear door to find the unconscious man. Then he dragged him out onto the ground. The man ended up paralyzed and having both his legs amputated.
