If the government wanted JFK dead or some other government or relatively powerful group then why oh why would they do it at Dealey Plaza?
Lee Harvey Oswald being the primary suspect makes sense because he was just a citizen and his best chance to assassinate JFK would be when JFK visited his hometown.
The problem I have with Grassy Knoll / Behind the Fence man is this. I live near and visit Dallas frequently. I have been to Dealey Plaza countless times. What I don't think some people realize is that the "knoll" is not a small hill going up and over. Immediately behind the fence / wall at the top, is a parking lot and railroad track area that is flat as a tabletop and extends for hundreds of yards in all directions exactly the same as it did in 1963. Where did the shooter go? I know there are about a billion theories. Guy next to a pick-up, hobos, etc. But, seriously, how was the guy not noticed by the LEOs positioned in the area for the express purpose of keeping it clear?
I think you need to evaluate your statement. The Zapruder film shows that the fatal headshot forced JFK’s head backwards, which proves the headshot came from the front, from the Grassy Knoll direction. Some of his brain matter was blown out of the exit wound at the rear of his head, landed on the back of the limousine, behind JFK and Jackie. Jackie Kennedy crawled onto the back of the limousine and tried to collect it. After she got back to the backseat she said “They’ve killed my husband, and I have his brain in my hand”.
Though I don't doubt the doctors sincerity... the underlying problem with his discovery is that the head shot was from the rear. Proven time and time again by ballistics and autopsy photos.
From the confession of James Files 1994: "When I got to the point where I thought it would be the last field of fire, I had zeroed in to the left side of the head there that I had because if I wait any longer then Jacqueline Kennedy would have been in the line of fire and I had been instructed for nothing to happen to her and at that moment I figured this is my last chance for a shot and he had still not been hit in the head. So, as I fired that round, Mr. Nicoletti and I fired approximately at the same time as the head started forward then it went backward. I would have to say that his shell struck approximately 1000th of a second ahead of mine maybe but that what's started pushing the head forward which caused me to miss from the left eye and I came in on the left side of the temple."
From the confession of James Files 2003:
J - where were you aiming?
JF - Oh, I was aiming for his right eye, which to me is the left side of his head looking head on. But for him it would be his right eye, and when I pulled the trigger, and I'm right in on it, and it's almost like looking 6 feet away through the scope. As I squeezed, take off my round, his head moved forward, I missed and I come in right along the temple. Just right behind the eye.
J - Here or in the hairline?
JF - Well, I'm not sure, you know I can't see the penetration, I know I hit him right here (pointing at temple). I know I hit behind the eye. Somewhere within a half inch diameter right there (pointing again).
W - So there were actually two shots almost simultaneously?
J - You think he got hit as you squeezed?
JF - What I believe is this : ….. And I got my readings as a marksman, I'm a good shooter, always was, I'm not bragging on my stuff, don't get me wrong, but that's what got me my start with David Phillips. Because of something that I did in the service, and I made a mark there and it's on record and it's recorded, for headshots, for what I did, and the things that I did. But anyway, to make a long story short, as I am preparing to squeeze off my round, Kennedy's head moved forward, just as I squeezed. It was already in process, the head started forward. To me … what I believe is, … and I did not see, let me clear the fact now, I never saw Mr. Nicoletti shoot Kennedy, but I know he was the man in the Daltex building, the man supposed to be doing the shooting. Therefore the head started forward and as far as I am concerned Mr Nicoletti hit him at that point. As I squeezed off my round, the head started forward, I hit it and blew the head backwards.
