Eh, downvotes happen. (Admittedly, I'll be less enthusiastic about sourcing in the near future...) I suspect 'AmericanChopper has learned something ITT, which was the point. He had a particular understanding of this practice, which had been imparted by someone he trusted. Now he knows that understanding was... incomplete, let's say.
ProPublica can bang the drum all they want. In USA, the big media firms are all controlled by very rich people who don't want this sort of story to stay in the mainstream consciousness for more than a couple of days. So, information like this disappears more quickly than the average citizen can understand it.
