I just heard an NPR story about a program to keep sex offenders locked up after they've served their sentences, but to keep them on treatment programs. The idea is to fix them before releasing them; the concern is that it's really just, y'know, keeping people locked up forever. I can see arguments on both sides, but the shrink who oversees the problem was quoted as saying (in paraphrase) that sex offenders are subject to greater concern than violent offenders because sex offenders undermine our basic value system.
Well. Um. Of course rape and molestation go against any worthwhile value system, but I'd argue that value systems which give criminal violence a pass are crappy value systems that need to be phased out. Maybe I'm not red-blooded enough for shrinks who work for the government.
