When I was younger and living in Amarillo, it was well known that the cops would stop the elevator between floors and work the individual over. Happened to 2 guys I knew. One probably deserved it, but he had his hands cuffed behind his back when he was beaten. And he had no marks on him when they put him in the car, but had two black eyes and other facial injuries when released. But he was released the next day without charges.
