David Von Peinhead has got the entire WFAA coverage of the Oswald shooting up on his Youtube channel. It's a long video, over an hour, and the Bill Lord footage of the shooting occurs towards the end.
I watched it with my index finger on the Print Screen key, and I couldn't capture the glimpse of "Ruby" gazing at the camera until I slowed it down to 1/6 speed, which you can do on Google Chrome.
And this is what I got:
All I can say is: how dare you? How dare you claim that that is Jack Ruby or, for that matter, Oswald's shooter? He is not either one. That round bald head is certainly not Jack Ruby's.
What an appalling and outrageous claim. It is truly a crime.
