Prison should be a place where people are placed that CAN NOT live a life without putting harm towards other people.
There are so many innocent people getting hurt, killed, rapped, robbed, every day and the ones who do this still flood the streets. As bad as this sounds, they should have an island or something where these people are sent until they prove they can be civil and not harm others in any way.
But the "system" would collapse if this were to happen. The governments need these people to do evil towards others. Its sick.
