Starting at 1:24 ...... this reporter guy looks right at - Jack Ruby ..and then shakes his head at him like 'Gotta love it'.
There's a longer version of that somewhere out there Jerry where IIRC, he's not smiling at him but clocking him hard, like he's concered and Ruby leans near him and could almost mutter something to him. I'd love to know who that reporter was and if he went on the record with anything significant.
Also that line "mind the car", beautiful.
I see the vehicle pulling up snd honking as a distraction, that would have needed to be coordinated with someone outside who could see them coming and give the driver a nod. Correct me if I'm wrong but LHO was leaving in an armoured truck, not a low vehicle with windows easy enough to throw bricks through.
