I was 17 years old and in high school when the announcement came over the PA that the president had been shot in Dallas.

The first thing that crossed my (weak and shallow) mind was that Vaughn Meder was out of a job. If you remember him, you're as old as I am.

Oh yeah, I saw Ruby killed on live TV. Freaked me out.

And...I lived it, I watched it, and I followed the aftermath closely. I am utterly convinced, by simply watching what went on at the time, that there were AT LEAST TWO SHOOTERS. Period. So was most of the country at the time just as convinced. The keys for me....
(1) EVERYONE turned and looked up the grassy hill for the shooter.
(2) The films show Kennedy being hit twice all right, but the second (fatal) shot was from the front.
(3) Bullets do not go thru a Texas Governor twice, make a right turn in the air, and hit a President in the back of his head.
