Yeah, it seems this guy’s life was a bunch of fronts. He had to be an infiltrator of some kind. Could be KGB, arabist-Sovietist deep state CIA, ISI, who the heck knows.
He could have been dead before the shooting started, his girl friend sed he would lay in bed screaming and making comments maybe he knew his time was coming and he had to pay the price and was used as the perpetrator for all time.
