Therapy doesn't have great outcomes for sex offenders.

There are different types of sex offenders, hiring a prostitute can make you a 'sex offender', but using this kind of loaded language implies something much worse. The type of offenders with poor outcomes are offenders who's ACT was inherently criminal (rape, pedophilia), in this case the act he committed (masturbation) isn't inherently criminal, it was where he was committing it (in public), and the fact he is likely too mentally ill to realize his efforts to hide what he was doing were ineffective (this kind of problem is treatable). There is a difference between lacking impulse control, which this individual clearly does, and being a dangerous predator beyond redemption like a rapist or pedophile.

How 'great' are the outcomes for putting sex offenders in jail, I hear thats not great either, yet the taxpayers are gonna have to foot the more expensive bill for this
