At the very end of the video, Creepy Joe says that the prosecutor was replaced with one who was “solid”.
So, the “official” explanation seems to be that the prosecutor was either corrupt himself, or incompetent.
And that really means that the prosecutor wasn’t effectively sweeping the corruption of high government officials under the rug as he was supposed to do.
I just found the entire CFR session on youtube. It’s 59 minutes long...I’ve watched 15 so far (all I can stomach right now...time to go back to bed) but will finish it later to see what led up to his ‘bragging’. Yeah I caught the ‘solid’ part. Right you are...had to have someone who was thoroughly corrupt to ‘hide’ their activities.
