I mean, not to open that barrel of worms again, but the accuracy does strain my credulity.
From wikipedia:
“During his Marine Corps service in December 1956, Oswald scored a rating of sharpshooter (twice achieving 48 and 49 out of 50 shots during rapid fire at a stationary target 200 yards [183 m] away using a standard issue M1 Garand semi-automatic rifle)”
Kennedy was 81 meters away from the book depository when the fatal shot hit him
