I want to take up several of the points you and Swordmaker made, but it will have to wait until later this afternoon. It's circa 10:30am Pacific time and, although I'm off through the weekend, I have an office lunch to get to by 11:30.
I'll just conclude this post with two points: Acknowledging the truth about any point of detail regarding the assassination does not preclude a conspiracy. If you watch the Zapruder film in real time and in slow motion, as I have many times, there is no doubt whatsoever that the upper right front of Kennedy's head explodes outward toward the right front, and upward. And yes, I'm emphasizing "explodes" and "explosive" over and over again in this thread because that is exactly what happened. I posted the full sequence of Zapruder frames so people could see for themselves as much as is possible without seeing the motion.
Thanks - that's part of the fun of Free Republic.
