Here's my theory. Now I'm getting myself into the mix....LOL. The Warren Commisssion ASSUMED that there were 3 shots fired from the TSBD in about 6 seconds. ( Give or take a second or two). No where in the WC reports is there any reference to the change of trajectory, the 'load" of the bullet. the difference in distance of the shots, the realigning of the sights, the fact that the " alleged shooter" had to account for an obstruction in his sights, and most importantly....that the gun he "allegedly fired" was capable of producing " 3 consecutive" shots with the same velocity and the same accuracy as the previous ones, period. We are asked to assume that the shooter from this sight could be an expert marksman with incredible skills who could outshoot any reasonable person with basic shooting skills and then, walk away and calmly hide his weapon and escape undetected. I DON
T BUY IT FOR ONE SECOND. Sorry. It makes no sense to me.
You're really starting off on the wrong foot, Dale. For starters The WC didn't assume anything of the sort you're claiming but based their conclusion that three shots were fired based on the overwhelming earwitness testimony that three shots were fired, that three empty hulls were found on the 6th floor SE corner of the TSBD (the SN) and that there was no credible evidence found that shots were fired from any other spot. That 6second timeline was based on the Z film were it was calculated that 3 shots could have been fired between zframes 210-25 and 313, so divide that by 18.3fps (as calculated by FBI experts) and you get a range of 4.8 seconds to 5.6 seconds if, and this is very important, the second shot missed. If either the first, or much less probably, the third shot missed then the time span of the shots would be expanded by at least 2.3 seconds (the time calculated for the bolt to be operated). This would increase the time span for three shots to 7.1 to 7.9 seconds. But the WC also indicated that the time span could have been greater for the three shots if it took longer for the shooter to work the bolt and aquire it's target. This is all in the WRpages 110 - 117.
The trajectory and distance were covered in the WR between pages 96 and 110. The load of the bullet was determined to be on average about 160 to 161 grains and the obstruction of the Oak tree was covered when it was found that branches began to obstruct the shooter by zframe 160.
