Mark David Chapman was not interested in the Beatles. He lived in luxury in Hawaii with no visible means of support, spending his time buying expensive paintings. The US government to him to Beirut. The day before he hunted down Lennon he had a long meeting with the FBI in Detroit. After he shot Lennon in front of the Dakota, he froze, took out "Catcher in the Rye" by JD Salinger, and started to hypnotically rock back and forth reading the book compulsively, even though there was a subway entrance 10 feet away, and the human thing to do is to flee after committing a crime. His psychologist was the same guy controlling Sirhan Sirhan. Yoko Ono says that "They" killed John Lennon, not "He" killed John Lennon.
This, from an alt.atheism newsgroup "regular" who is known for his elaborate takes on September 11, the moon landings, alien visitation...it's recently come to his attention that a pair of proper group regulars are in fact paid government plants:
to secretly infiltrate “chat rooms, online social networks, or even real-space groups” by using ostensibly “independent” credible voices, who are actually secretly in the pay of the government, to counter “conspiracy theorists” such as the 9/11 Truth movement and other “extremist” groups. They dub this program “cognitive infiltration.”
...because they have the nerve to disagree with him. Guess I'm Part Of It too, now that I've smirked at him here. Where's my paycheck, Mr. Obama?
