Grabbing some girls butt in high school today gets you on the list. fyi.

Sex offenders are not out on serious things like rape. It's usually fondling, public display, adults, kids, elderly, perpetual public urination, child porn etc. Serious ones are sent up for a period of time and then released and have to be monitored by parole/probation.

So far, they are not curable either, so the system is still trying to figure out what to do with them. Monitoring is the best thing available, not enough bed space for them all.
