It's not necessarily that they were turned. The fact of the matter is that good people were under a system that compelled them in certain ways. If the result of acting like we do and shouting piss and vinegar all over the place … Is to end up mdked or strung up on unfair charges (or for crimes committed by your superiors) - then the whole system becomes one of keep your head in the cubicle and hit the rubber stamp.
Smart people who managed to get higher in that system would make very good notes and put them in places that could be accessed in the event they got brought up on charges for shit their boss told them to do.
