Somebody above said there's no need to understand the reasons behind child molestation.

No they didn't!

If you don't understand a criminal activity thoroughly, you'll never be able to figure out how to control that sort of crime.

Not true.

Shooting "bad guys" with guns just isn't very effective.

Also not true, though no-one has suggested anything of the sort, and I certainly wouldn't condone it.

NO CATHOLIC favors the crimes of molestation and abuse and coverups that took place in the Catholic Church.

Blatantly not true, otherwise this discussion would not be taking place.
