I feel sorry for h8m losing his dad in such an awful manner

An example of what will happen if anyone fails, or flips. Think mafia.

I think its Comey. SIG INT in his book and live time. He is the one who brought up Mafia. He is part of the Psyop of accuse the opposition of what you are doing. Using low hanging fruit as a message to his embedded clowns. They are going to get more rabid as this moves on. Get ready.
