Watched last night..it was very convincing and even plausible...but I always fee that way every time I watch a show like that with a new theory...we will never know for sure what really happened and who was responsible...well maybe Arlen Specter did..lol
I'm not ready to completely accept all their theories yet. The angle theory is literally shaky because the slightest movement by Kennedy could change everything. The 'smell of gunpowder' could easily be simply the power of suggestion. They are asked if they smell something, in hindsight they think about it and their mind builds a pattern.
The type of bullet, FMJ versus frangible is pretty compelling. I was unaware before of the number of fragments in the headshot. That isn't a FMJ that hit something sold versus the other bullet going through soft tissue.
I believe it could be very plausible that a SS agent did accidentally shoot Kennedy and there was a cover up to not cause a national damnation of the Secret Service over an accident. Not a nefarious conspiracy, but a cover-up of a friendly fire accident during a chaotic situation.
