Can anyone tell me what episodes are about child molestation. Please I am trying to solve my own case.

I think about half of the episodes are about child molestation!I say this not in jest...I just saw Chris meloni on Regis and kelly this morning. Meloni was saying he never watches the ones about child molestation...interesting. There was a bizarre episode I saw last week from early seasons. These professional men- doctors, dentists, even a travel agent were going overseas and adopting pre-teen boys from their countries, bringing them to NY, and sadly abusing them. It was very disturbing to see. Don't know the name of the episode,unfortunately. Maybe they dealt with the subject more in older episodes.Disturbing as hell! Oh Susannah....
