I first entered Louisiana State Penitentiary in the early 60s, at the age of 18. I was in and out of that place for the rest of the decade. Back then, if you were young, black and had a record, police in New Orleans would come looking for you when they had a backlog of unsolved cases: it was called cleaning the books.
In 1969, I was locked up for a robbery I didn't do and, while inside, I joined the Black Panthers. Three years later, an inmate was stabbed to death on my prison block and, because of my politics, the authorities saw a chance to pin it on me. In 2001, I was cleared of this killing but, by then, I had spent 29 years alone in a cell.
It was a dimly lit box, 9ft by 6ft, with bars at the front facing on to the bare cement walls of a long corridor. Inside was a narrow bed, a toilet, a fixed table and chair, and an air vent set into the back wall.
Some days I would pace up and down and from left to right for hours, counting to myself. I learned to know every inch of the cell. Maybe I looked crazy walking back and forth like some trapped animal, but I had no choice – I needed to feel in control of my space.
At times I felt an anguish that is hard to put into words. To live 24/7 in a box, year after year, without the possibility of parole, probation or the suspension of sentence is a terrible thing to endure.
I was kept in the closed cell restricted (CCR) wing of the penitentiary, which is also known as Angola, after the slave plantation that was on the site prior to the prison. Three times a week I was let out for an hour to go to the exercise yard, where I was kept separate from other prisoners by razor wire.
The wardens tried to discourage us from talking, but we defied them. We were beaten up and prisoners were found hanging in their cells. Whenever I was disciplined, it was for talking. I didn't care, I refused to let them dehumanise me.
