While I agree with a lot of the criticism folks have posted here, I also am sympathetic to Joe's position. He grew up within this church and is attempting every day to do positive things and change what he can.
Joe asks.."So, hey, does anybody have any really good ideas on how to detect and solve the problem of child molestation? "

Yes... I do, but I have NO notion that there is much chance they would be taken very seriously, as some of the problems are built in to the very structure and routines of what the Catholic Church believes and into their basic practices.

One: Although it is, as Joe notes, possible for ANY institution to have its share of abusive, degenerate members, the **Catholic** church has this basic restriction against married priests..(yes, I know there are minor exceptions, but it IS the usual way.) This exacerbates whatever problems already exist. Our evolutionary heritage and basic biology do not recognize 'chastity' as a natural condition. When men and women are housed and taught in an environment of almost all members of their own gender, a different set of temptations are encountered, and 'some' people have less personal resistance. Add to this the common perception among those already tending toward deviant behavior, that 'the church' is an easy way to indulge without serious restrictions, and you get an ongoing problem!
Two:There are a few situations which create opportunity that are specific...for example, confession. Priests hear things which MUST be hard to sublimate, even for those with GOOD intentions. (There is a joke about a Rabbi who is asked to sit in for a priest who is called away....and the joke ends with a friend asking how it went, and the Rabbi replying, "But I did get a few good leads!")
There are, as I understand it, several situations where personal 'counseling' is part of the plan.. (I am NOT familar with all the details)...and it seems to me that this invites tempation.
Three: The very complex and structured hierarchy itself contributes to the tendency to hide, rather than cleanse, problems. Bad publicity is often treated as a worse problem than the offense, and offenders are 'counseled' and 'moved' and records are hidden.

I can't see most of these basic items being radically changed soon.....but that's what I see as would be necessary.
