There once was a place just outside Atlanta with realistic jail cells, solitary confinement and a padded isolation chamber. It was a place where you used to be able to go and — for a fee — have real cops and military guys (supposedly straight, but who knows) lock you up and work you over. When they were operating under the name of the Jail Training Center, I went twice. Here is a picture during my first visit of my boots when I was locked in one of their cells, and another picture during my first visit of me hogtying a guy.
There is also some video out there somewhere of me helping restrain another guy in a straitjacket, which I have never seen. I have since lost touch with the guy who was running it, and I am not sure if the place is even still in operation. If it is still running, I am not aware of it. Before the place in Atlanta, they also had a facility in Missouri. It was also called The Academy.
