Mike....if you want to prevent future molestation of innocent little kids....you don't just throw the priest out...so he is now a potential public offender with little or no oversight.....rather you keep him in house in the system but very strategically placed and herein lies the difficulty...

As I recall in Philly, there is a treatment center that is supposed to house these guys AND keep them contained  but I also recall that on Catholics 4Change there has been much discussion about the effectiveness of this "containment"....

I recall an Order that houses its own guys that allows them to wander in an area complete with both a grammar school and a middle school...again it's all about supervision...which is costly and as far as I can figure out relatively naive in its trust ("we trust father, dressed in civvies, when he signs out to go where he says he is going") and slovenly in their management style.

My criterion would be what system  protects a potential future victim best?
