I wonder what people will think of criminal and justice systems after this (probably nothing). We send people to prisons all the time for extended period without outside contact in an abusive environment between the real nasty criminals and authorities. Is it really a good idea to send someone to prison for months for a small mistake that many might end up making and getting caught? Is overusing imprisonment for different types of crimes okay? A murderer will be fine in a prison since they are harmful for the society but someone stealing food because they couldn't afford any doesn't seem as harmful that they need being locked up.
