^ Yes, researchers have tried to explain the slight forward head movement before the "back and to the left" reaction as one shot from the rear followed immediately by the frontal shot. Years of lab trials using incredibly high speed photograpy have now proven that, in the case of ballistic skull wounds, the head moves into the bullet, against the bullet's direction of travel. I have also been working on a video that explains how, following the slight forward movement, the shot from the south knoll produced a transfer of kinetic energy causing the "back and to the left" reaction as explained in "Enemy Of The Truth."
As for the audio evidence, it has always been a big point of interest to me & you may recall that I tried to replicate shots at points in the Z film suggested by Bob Harris here in the studio. The problem I have encountered is the ambiguity of the existing physical audio evidence combined with the unreliability of conflicting earwitness testimony. There is an entire chapter on earwitnesses in "Enemy Of The Truth". IMO, "Bang ... bang, bang" still suggests that the Carcano couldn't be fired so quickly but the new forensic evidence trumps that, no? It proves at least 2 shooters were firing, as we know Governor Connally was hit from behind, and again, the one and only head shot came from the front.
Another point I have come to realize is that in all of the previous audio trials they would have to have placed all trial shooters in the correct positions (south knoll not included?) to achieve matches to existing audio evidence. I don't believe the consideration of the location of the open mic to the dictabelt was done with much precision either. Results do include one sound attributed to a firearm with no match to a location. Considering all possible backfires, fireworks and rifle reports confused by the echoes of Dealey Plaza, I am less than optimistic that we can ever nail anything down with absolute certainty. I wouldn't bother to argue with Mr. Harris after he insisted that I should continue my audio study as if done from within the limo, trying to corroborate the ear witness testimony of the occupants. I tried to explain that the limo occupants were within the 10 ft. radius of any bullet that found its mark inside the vehicle so the simultaneous nature of the "sonic boom" would make that shockwave the only audible sound to the occupants and not the rifle report. That leaves it impossible to believe, with confidence, that earwitness testimony from within the limo could place the direction of origin for the shots that enterd the limo.
Well, that's what I have for now. Thoughts?
