I rarely get out the tin foil, but I’m starting to wonder about a second shooter, possibly on the water tower. That would explain the cryptic video message that the shooter left “guess what, you got the wrong guy”, and it would explain why his aim was so bad and the crowd shots were so far away from the President. Maybe his instructions were that he was not to start shooting until after he heard the real first shot. He was convinced/brainwashed to be a martyr for “the cause”
