Something has come up which supports my contention that Jack Ruby got to the ramp earlier than 11:17, and Lt. Pierce made two exits. It is that when Pierce made his 11:17 exit, he had two other officers in the car, including one in the front passenger seat, which was on Ruby's side. So, how could Ruby see Pierce, as he did, without seeing this other officer? But, Ruby did not see him. And that suggests to me that Pierce made two exits, and he was alone the first time when Ruby saw him.
