I used to say the same thing this HSCA member said. I'm happy to find the first person agreeing with my theory. According to CTers, Dealey Plaza was the perfect spot for killing JFK. Many Dallas persons wanted to kill him, so it's very possible that they noticed it. It is also possible that a second gunman, and possibly a third or fourth one on either side of the grassy knoll were surprised by Oswald's shots that they froze and did not use their guns!
