Did the independent witness who thought all the shots came from the GK corroborate the other independent witnesses who thought all the shots came from the GK.

It appears from his testimony that he hadn't really thought about which shot hit him, other than recalling that it wasn't the first.  When asked about it whether he heard a shot afterward, he thought and said he did recall hearing a shot after the shot that hit him. Since he heard only three shots, he said it must have been the second that hit him. 

But I agree, by itself it is not reliable.  What makes it much more reliable is the rest of the evidence. 

According to the shot pattern observed by over 40 witnesses, the last two shots were close together and after the midpoint between the first and third shots.  That means that JFK was struck by the first shot (as about 25 witnesses reported) and the second was after z255. The second shot struck JBC in the wrist and sent numerous flecks of lead into the wrist and made a long jagged hole in the french cuff but a non-jagged hole in the jacket pocket and jacket cuff.  That is not only consistent with a fragmenting bullet, but also with the fragments deflecting away from the point of contact with the radius.  The orientation of the wrist up near his chest exit wound after z240 means the fragments would have deflected up.

Greer said that he sensed a "concussion" from something impacting in the car on the second shot. The damage to the windshield frame was just above his right ear. He reported no impact sound from the other shots.  Greer said the second shot was almost simultaneous with his first turn to the rear (z281) when he saw JBC falling back.  We know that on one of the shots fragments struck the windshield and windshield frame. It is at least interesting that the left sun visor appears to move forward between z271 and z272:



A fragment striking the windshield and frame and at least one fragment going a bit higher and striking the road and curb near Tague is consistent with the second shot fragmenting and deflecting upward off the wrist. 

It is not impossible that Tague was wrong in thinking he heard a shot after he was hit, but that would mean that he was hit by a fragment from the head shot. The only problem with the head shot causing the damage to the windshield and a fragment going up over the windshield is that I don't see that it struck anything hard that could have deflected it.  It likely fragmented upon striking the back of the head but that did not change its direction. The bullet or bullet fragments passed through the head and exited on a downward trajectory from the SN.  So I don't see what hard impact would have caused a fragment to deflect upward after that.

Why would anyone be "genuinely interested in the issue of Prayer Man". When he CTs obsess over something this inane, we know the carcass of the JFKA conspiracy "research" has been picked clean to the bone. There's obviously nothing important left that is worth talking about.

I dug up the research your File Locator Number discovery inspired me to build on!
