"back ... and to the left.... back... and to the left... back..... and to the left..."

I've heard lots of theories, I'll list them here for people who are interested.

1. Gov John Connolly was armed with a pistol, driving the car, and when he heard Oswald shoot, he turned and fired, blasting JFK with his pistol at short range.
2. There was a shooter in the storm drain with a rifle,
3. There was a shooter(s) on the grassy knoll.
4. There was a shooter under the overpass.
5. There were multiple shooters who triangulated JFK from multiple angles to make sure the job got done.

I don't want to rain on anyone's parade, but I concluded a while ago that the vast majority of "JFK assassination" material comes from the CIA itself.

I thought it was a shot from the front to the back.

I mean the back of his head was blown off and it blew back onto the surface of the car. Jackie said she was trying to scoop it up from the trunk of the car after the shot. That was why she was hanging out of the car for a little while right after the shot. She instinctively climbed back there to scoop up her husband's brains and skull after it blew out the back of his head.
