Thanks for the link GT. We can skip JoePa. The rest of it sounds all too familiar as far as the way a perp positions himself. My CSA, too, was the same time as yours.
My perp was heavily involved with kids: BSA, church camp, HS teacher and guidance counselor, professional societies AND had wife/kids. An article written after his death goes into neauseating detail about the years of personal work and improvements he made to the church camp (including cutting a new trail to the boys cabins - go figure). To read it you'd think the man was a fucking saint. And, moving from teacher to guidance counselor, he put himself in a position to "help" troubled young teenage boys, like me. Bastard.
I'll add that 40 years on - though I can't speak to "community practices" - the institutions still have their heads in the sand.
