Spent nearly a decade doing data analysis for the corrections system. Just one small part, but we interfaced with many others in different parts of government, academics, and NGOs, spinning our wheels discussing how to implement progressive reform, reform we have had mountains of hard evidence corrects a lot of problems, especially reducing recidivism. The big hurdle wasn't corrupt politicians, or privatization of the prison system (not saying those weren't major problems, just different ones) the big issue was that the average person is vicious, and wants to sit in their house, seeing "bad" people on a screen, get destroyed by the system. A HUGE portion of the population have a vicarious blood lust for seeing people get punished, the harsher, the better. This allows for the punitive system we have, which makes it an open field for other predatory practices. Suggesting anything to the counter will not get anyone elected, and will stir backlash from throngs of morons asking why we should do anything less than just execute criminals on the spot.

Those who don't either are a minority that grew up differently, or had this unjust bloodlust targeted at them, or someone they care about.
