Mcgreevey had a lot to say about this years ago. He mentioned E Sullivan being bmailed by Rosenstn & others over his son mrdring a hkr in their home years prior and bureau finding out but just held over him. Said they came to E Sullivan and son to carry pipe op but that son got cold feet last minute and someone else did it.
It's disgusting how internet sleuths can fuck the FBI up the ass on a case like this, almost like they weren't concerned with finding their man, or woman
