Looks like they destroyed the Link back to the FBI and /or other FED's.
Remember - the Dad of one of these was the "Brainchild" of the 1993 WTC Bombing. And right before that bombing, the Snitch wanted/Asked the FBI to use FAKE Explosives instead of the real stuff... But in their spectacular judgement, the FBI pushed him to go ahead with the real explosives.
Ignoring local complaints, Covering up evidence.... Sounds like everything the FBI (.Gov) is involved in.
Government = Terrorists. They need to justify their existence.
I'm not saying that these guys are not terrorists by themselves, but there is deeper help.
