Video from which stills are taken:
The screen stills before the shot that hit Kirk do show his earpiece but that same area is more vivid in the stills immediately following the shot.
This looks suggestive to me but not conclusive.
IF an Israeli-style exploding device armed with a self-destructing projectile is what caused Kirk’s death, what we can see in these stills might support that hypothesis.
IF he was shot from a rearward vantage, the movement of his head is well explained as is the exit wound on his neck’s left side (not seen in the above video).
IF he was hit by a bullet, it would have been a small caliber. But where is it?
IF he was hit by a self-destroying mini-missile, the evidence we see fits well.
IF he was killed by an Israeli-style self-destroying projectile device concealed in his earpiece, the video evidence also supports this.
All of this is speculation based on the low level of information available to the public. I dislike the way the FBI appears to be playing games with us through its meagre releases of information.
This is no longer 1963. Or is it? ABN
