Lord Acton proven right again, re absolute power corrupting absolutely.
The saddest part is the enabling, protecting, defending of the predators - not by their organization, that's standard, look at Penn State and Sandusky, or the Olympic Committee. But by the "flock". Even parents of some of the abused didn't want to believe their own children.
Oh - not sure if this has been noted above, but similar scandals are emerging from ultraconservative Protestant areas nowadays (Bill Gothard, for instance, and yes that is a horrible aptonym), and there was at least one involving an orthodox Jewish community (Hardei, Brooklyn). It's not a specific religion that drives this; it's the worship of power.
