Seems to that for those people who can't be blackmailed, threatening their family "from a position of credibility", kinda like the Mexican mafia offering the blackmailee the choice of "the gold or the lead", would be effective.
It seems that the way to deal with such a thing would be for the target of the intimidation to just, uh, take care of the criminal apparatchik on the spot.
But that's easy for me to say, of course, not facing the criminal myself, at least not right now. Seems like Solzhenitsyn had something to say about that situation...
If the generals and SES's don't get a grip on Obama's Garden of Beasts pretty soon, the job will be left up to the NCO's and LTs. And it will be a much messier job.
