I was dumped into a cell without any medical attention or surgical attention whatever. My broken bones were not set. My ankles and legs were not put into a cast. The doctor never came near me and no one else was allowed to do anything for me. At the end of 14 months of constant agony, I was taken to the hospital where I was operated on for my rupture and one of my testicles were cut out….I suffered more agony for many months. Always in pain, never a civil answer from anyone, always a snarl or a curse or a lying, hypocritical promise which was never kept. Crawling around like a snake with a broken back, seething with hatred and a lust for revenge, five years of this kind of life. The last two years and four months confined in isolation with nothing to do except brood. I hated everybody I saw.
