Creative Speculation

A) You have not answered my point that witnesses can simply be wrong about where the sounds came from. B) You have not answered my point that it makes much more sense that those people were trying to get to the parking lot and leave than that they were rushing a murderer with a gun. C) You have not refuted my point that, to anyone who applies valid physics to accurate observations, JFK's reactions seen in the Zapruder film not only implies that the shot came from behind, but it completely precludes the possibility that the back-and-to-the-left motion was the result of momentum from the bullet.

Instead, you throw out a new claim:

> And yet, there is no evidence that a gunman situated in the front was ever considered by the investigating authorities, rather it would be quickly determined that the assassination was the result of a single shooter with no associates.

As stated, that is simply not true. There is in fact ample evidence that the DPD, the FBI, the Warren Commission, and the HSCA all considered the possibility that there were other shooters. There's a reason they came to the conclusion that there wasn't: Any other conclusion would have required actual evidence beyond where some people thought the sounds came from, but none was found.
