Maybe Oswald was actually a cyborg from the future with superhuman capabilities...

I do not recall any mount being involved.

If the jacketed bullet went through Kennedy and Connolly and hit bone and stayed intact, even through 48" of pine.......why didn't it travel through and through his skull instead of disintegrating totally?

The other side of the coin is with the testing/reconstruction that was done it done appear the one bullet was from the front.

Exactly my point; for this type of precision shooting, a mount is a necessity. I believe the people behind the assassination knew they would never get a second chance. So they carried it out using multiple shooters using a classic military sniper style triangulated cross fire method. Once the car crossed into the kill zone, they let loose.

Craig Smith talks about this in much deeper detail in his book:

I think if you saw this presentation, you might think differently.

some say because the final shot was fired from an AR-15 (5.56mm) in the Secret Service car following the President's car and it was an accidental discharge

Get access to the show I linked.....he proves it with forensics.

He shows a hole about 6mm in the back of JFK's head and the hole in his back about 7mm all documented at autopsy.
5.56 and 6.5 mm.

Secret service....Ooops.

What caliber is an ar 15? would it have had ordinary lead bullets and not full metal jackets?

Civilian equal is. 223

The explanation about why his head flew back on the last shot--- no way i buy this, and never will.
Its safe to say most everyone here knows how people / mammals behave when they are shot. This would be the first time that someones nerves made them behave in the way explained.
ive been there more than a few times--in the museum etc.
I was born one floor from where they took him 75 days from when it happened.

The Secrets of the Dead episode that followed was possibly the most worthless waste of effort put into any show recently.
All about Walter kronkite and being first to have the exclusive -deliver the news.
who could care less?????

That's what a friend told me last week, that he was surprised of how small the area was where it all happened. That what he had seen on TV was deceptive.

Where does the timeline of two or three seconds come from? The investigations I've heard of all say between 4.5 and 8 seconds. Which is certainly possible for a competent marksman.
