True as it is that the FBI and other agencies were making his life more difficult the gunman just sat there and read He shot him and sat down he was apprehended and confessed without a fuss Why would a man serve 20 to life for some minor grudge with his politics I remain pretty convinced this guy was a loon now I don t know if he was somehow pushed or encouraged to go this route but without some amazing new information I ve got to conclude that John was murdered by a fan in the truest since a fanatic
