What part of 'manners' don't you get?
When JFK is struck at z312 the knoll is to the front right of him so when you say "from the knoll, not the front" it makes you sound like you don't know what you're talking about.
A shot from the overpass?

Whereabouts from the overpass? Who witnessed this? What evidence do you have for a shot from the overpass?
Manners? LOL. You're just like my wife, you sense "attitude" when there is none. I am not offering proof of anything, it's my best guess using logic based on the facts. You are asking me questions as though you didn't read my posts. I answered all your questions up thread. I guess you just don't want to hear them.
The knoll shot was side-front using a frangible bullet that blew out a perfectly circular 2 inch diameter hole at JFK's right temple. This was an entrance wound that blew out when the bullet exploded creating a skull hinge on the right side of the blow out.
The overpass shot was full-frontal. I assume there was a shot from the front because JFK had a fist-sized hole in the back of his head. This had to be a blow out from a frontal shot which was an exit wound (if a FMJ bullet was used). I placed the shooter on the overpass because that matched the trajectory of the bullet that blew out the hole in the back of his head.
Those 2 shots are responsible for JFK's motion, "back and to the left". I also explained why the placement of a blow out hinge on the skull does not necessarily indicate where the shot came from.
JMHO of course. It certainly wasn't Oswald taking a shot from the TSBD that simultaneously blew out JFK's right temple AND the back of his head. So if it wasn't Oswald shooting magic frangible bullets then....you tell me.
PS. "Overpass" is inaccurate. The frontal shot came from the tracks to the left of the overpass. (see graphic up thread)
