Here's an incident that took place last week in a town near me:
A man with a beer and a condom approached a random couple on the sidewalk and declared his intention to have sex with the woman. When she declined, two of his brothers and a fourth man appeared from behind a bush, beat the man into submission and dragged the woman back to their apartment. They barricaded the door and raped her. The criminals had multiple previous charges including DUI and were illegal immigrants AND they had sneaked into the U.S. a 2nd time.
But I suppose letting them "live with and be closely supervised by a family" will straighten them out. /s
What the author doesn't acknowledge is that prison is the best thing we have come up with so far. We all want something better, but we don't have it. And his touchy-feely concepts are perhaps adequate for shoplifters and soft-drug offenders, but not a family of gang rapists.
The true problems with the prison system are the overwhelming numbers of non-violent offenders who are disproportionately ethnic minorities. It would also be a good idea to improve rehabilitation efforts.
