Oswald did shoot JFK. He thought it up and did it all by himself with almost no advance notice of Kennedy’s route through Dallas or time to prepare.
He murdered President Kennedy with an entirely suitable surplus military rifle using domestically made ammunition. Firing his rounds at Kennedy at ranges between 44 and 88 yards, it was a dead simple shot for a man who learned marksmanship in the USMC.
The only conspiracy in the fact that Oswald murdered JFK is that legions of commie liberal hoaxsters have successfully persuaded a large segment of not very inquisitive people that any number of shadowy persons killed Kennedy for a wide range of absurd reasons rather than the truth that an unstable left wing whack job named Lee Harvey Oswald was alone in pulling the trigger that day.
Of course this means we are all a pack of dupes and simpletons who fail to see the sinister plot that has gone undiscovered for 50 years. Some of the people around here say they know the answer (but they refuse to share for some reason).
Whatever...
