When I was growing up I learned that, although not perfect, the United States had the "best justice system in the world." That bill of goods can not even be faintly passed off with a straight face to today's schoolchildren.
"Gas 'em 'till they puke" became the unofficial officers' motto back then -- so much so that, "You can still see it written on license plate frames in the parking lot."
Punishment is an important part of the process, like the tilling of a soil where only the inmate themselves can plant new seeds. But, if they're to grow, it takes a network of support that barely exists.
