Life in prison is hard, as it dehumanizes prisoners. Anxiety and boredom slowly creep in, and the void is to be filled in with drugs and violence. After the privatisation of English prison system, prison no longer rehabilitates, but brutalises and infantilises. Inside the prison you are merely a number and every day is grim and rough. This is ex-con Carl Cattermole’s survival guide and a detailed portrait of the political economy of English prisons for people facing incarceration. Family and friends cannot visit if their utility bills’ address does not match the ones on their passport. The Best paid job is the cleaning up of your fellow inmates’ puke and blood. Addictive drug like heroin is more popular nowadays than cannabis just because heroin leaves your body faster than cannabis, so it is easy to cheat a drug test. Phone call is now 15p per minute just for the sake of reducing cost. A university degree now tuition fee costs around £18,000 while it is free before. All these prohibited the ex-con to reform and return to the real world.
