Prisons are a private business in the USA. They're not that in Australia, that would be abhorrent to our sensibilities, that people have a financial incentive to taking someone's freedom, for any reason whatsoever. They make a profit, there are places in the USA where the major business in the town are the jails. One black guy got thirteen and a half years for possession of two joints in Louisiana. The CIA takes a ten percent or more cut from drug sales worldwide. The start would be looking at reasons why people commit crimes, who got killed, why? You can only blame genetics and environment for everything a person does, sure you may have to teach them a lesson, and sometimes they won't learn a lesson, but to me, the environment, the system is the thing that has to change, before you create another generation of people who can't be saved and need flushing down the drain, you created.
