The prison population was divided along paramilitary lines, with each prisoner responsible to his "commanding officer".

Appointments were then booked at the prison hospitality area on a random basis according to each prisoner's daily program and available time.
A prison guard, starts at the back of the line and asks each prisoner the colour of their hat.
Each prisoner costs taxpayers $43,000 annually.
Each prisoner costs £36,000 a year and most will reoffend.
Each prisoner is allowed one book and one magazine.
They map out questions before each interview based on a psychological profile of each prisoner.
