I totally agree with you Dj, there are a lot of injustices caused by these criminal minds. But even if we doubled or tripled the rate at which we locked these criminal minds in jail, they'd just keep on coming back. We'd have to attack the source of the problem by identifying the factors that produce these types of personalities/mindsets, then figuring out how to counteract it. It's no big secret that the highest crime rates are in low income/low education rate areas. I don't have the solution, but that's not a bad place to start looking for one.
