Care to back that statement up?

Crime and punishment is a for profit business. If you don't believe that... well then I don't know what to tell you. The War on Drugs, DRAMATICALLY increased the prison populations in the United States. States that saw an explosion in their prison populations and that we strapped for cash / didn't care to deal with the incarcerated (particularly southern states) turned to private industry to house their incarcerated populations.
> Money from where?
What money? Taxpayer money. And once private business get's a taste of blood, and politicians in the US get that first taste of kickback money, we all know where it goes from there.

If WE as a society decide that WE want to sent people to prison, WE should have to deal with the consequences of it. WE should be responsible for the incarcerated. WE should be who those prisoners are reporting to. After all, WE should have reform as the end goal. We should't have some black box prison company as the intermediary who's best interest it is to hush, abuse and prevent reform of prisoners in order to keep them coming and their pockets fat.
