Whenever I left my cell, even to walk just ten feet to the shower, I had to be shackled in leg irons and handcuffs, treated the same way as a prisoner who had violently assaulted a guard. For "exercise," I would be shuffled once a day to a kind of outdoor cage, not much more than twice the size of my cell, where for an hour I could breathe fresh air and do a few push-ups.
