Hearing from one guy that prison is easy... I did a report on this in government class, and interviewed at least fifteen (or something like that) of various degrees of security prisons (maximum, minimum, etc), they all told me similar stories and most told me anyone who says its easy is either crazy or lying. Every one of them said it was difficult, violent, and nothing they'd ever want to do again.

That does not, however, keep people from doing crimes. If they're going to be criminals, no threat of punishment will stop them. If it did, countries with public executions wouldnt have crime at all.
