I’ll ask again. Why not shoot Kennedy as he was approaching the book depository or directly underneath the sniper’s nest? Why wait until the car turns and is moving away? I’ll also reiterate my disbelief that a man who just murdered the President and gets out of the building and is safe at his place of residence, leaves the safety of that place and wanders the streets murdering a Police Officer. That makes zero sense.
Who knows? maybe some noise made Oswald hesitate. You ever shoot someone head on? unless you come up with something better, then sit down.
