If these acts have been used for blackmail, lots of images and videos must be lurking around out there...perhaps on a wiener drive... A sting operation, if appropriately managed and executed, could also be productive. The bigger problem is that these people exercise a great deal of power over law enforcement; if you have to choose between being fired/blackballed from an enforcement position -- or "suicided" -- there's a strong likelihood of a person backing down...particularly if they offer to pay your kids' college (and leave them alive) if you shut up.
