It is well documented that folks like Hugh Aynesworth concluded that these were related incidents when they first heard the news of a police shooting.
If that is so well documented...post these well documented statements--produced that day [not 3 weeks or so later]
It was also documented [that day] that some Oak Cliff gas station attendant called DPD around 1:30 [just before it was announced that JFK had expired]...and reported a couple of guys in a green station wagon [I believe] with a rifle in the back seat. They gassed up and drove off like crazy he mentioned.
This was reported over the police radio-- but no... this guy that was 'funny looking' and 'suspicious' brought the entire police department practically down to the theater in 5-10 minutes time.
Funny and suspicious to me was that there was not very much police radio chatter concerning the events at the theater but shotgun patrolmen and plain clothes guys sure arrived en force for a suspected sneak in.
