It's not often we get anything in return for our extorted tax dollars. But once in a while we do get a little entertainment, as in the case of Mr. Petraeus (formerly Gen. Grievous, with a record-setting number of Boy Scout badges on his suit).
We all know that the FBI hates the CIA, and vice versa, with a purple passion. This is always true among security organs, in any State. Not being mentioned is the even more bitter rivalry between the military and the CIA, which has its own secret army and has been seeking a massive expansion of it. Was the appointment of Petraeus to the CIA seen by that agency as a Pentagon coup? Did the CIA set out to get rid of him, by manipulating the FBI?
