I’ve stated the reasons I oppose prisons as a form of punishment before but didn’t mention one of the biggest problems with the incarceration system. Prisons are very expensive facilities because, in order to work, they need to prevent prisoners from escaping. Preventing an intelligent and creative creature from escaping is impossible because every system developed to prevent escape will eventually be bypassed:
Two inmates have made a daring escape from a prison in Canada by climbing up a rope into a hovering helicopter.
In order to prevent helicopter escapes prisons will have to either install anti-air defense systems or cage over the top of the facility. Both options are expensive and will simply delay the inevitable escape of future prisoners.
