The prison system is not what people imagine it to be - guards and inmates alike are subject to physical, sexual and mental abuse. Inmates and guards come out of prison with various degrees of PTSD.
Too many people fling out that old saw "If you can't do the time, don't do the crime", as if being tougher, meaner and less compassionate is what we need in ex-cons. They also forget that the same stresses prisoners face are shared in large part by guards.
The entire prison system needs an overall, but until our society understands that punishment is the least effective method of rehabilitating criminals, we're stuck in our current system.
Prison should be reserved for people who are "unable" to change -
**** who pursue their urges and sociopaths who prey on others, for example.
Drug related crimes, gang-related crimes, and similar are a combination of social and community failures, imo, but those prisoners have the best chance at leading productive lives outside of prison, if actual rehab was the goal rather than revenge and punishment.
The differences in treatment and sentencing between monied and poor criminals should be eliminated. But I guess that's just another pipe dream.
