I reviewed that testimony...
Mr Shields wrote earlier.....So, no there was no particular 'LINE' that Ruby waited in.
Ruby had no idea how long the people/person in front of him would be. Could've been 1 minute, could've been 10 minutes.
I have suggested before and still do that Jack Ruby was not waiting for Oswald's transfer but rather the transfer was waiting for Ruby.
Theres no evidence whatsoever to support this as even a fringe theory unfortunately. Ruby was in the WU at 11.17 (timestamped). He shot Oswald at 11.21.
Oswald was supposed to be moved at about 10.15am at the latest. Ruby was still at home then and had not even received the phone call from Little Lynn asking for money at that stage.
There was a delay of more than an hour when Chief Postal Inspector Harry Holmes arrived at 10am and to ask Oswald about his use of post office boxes.
Now even if somehow this was part of the plan, Ruby had no control over Oswald then asking for a darker sweater to look better in the TV lights. 5-10 minute delay. If he didn't ask for the sweater, the car would've driven up the ramp and away to jail with Ruby still standing in the Western Union. Or maybe still in his car on the way to the western union.
If Ruby was such a high level mobster, what was he doing taking calls from strippers for 25 dollars?! Who calls mobsters asking for that? Get up, drive downtown and send me money please. Certainly not broke strippers.
Every single person who knew Ruby well said its laughable that he could have been part of a conspiracy because he was so talkative.
Who takes out Ruby? Why wasn't he taken out? Mob style in jail, silently, no patsy. They just..... left him alone?!
