As I said above, Ruby hung around the station brown nosing the cops for years. He was a well known figure around there and made friends. All well documented. Security in those days isn't what it is today. Ruby's presence raised no eyebrows as he was there every week. Plenty of cops were used to seeing him. Ruby was hot headed and impulsive and used his familiarity with the cops to watch the transfer and do his deed. Plenty of reports on that.
Witness the fact that they put bullet proof vests on high profile suspects as they transport them to and from these days. Guess why? Jack Ruby is a big reason.
Guess why Presidential limos are no longer convertibles and are armored? Oswald!
I'll stick with the Warren Commission Report. Nothing else is nearly as timely or thorough. These were two opportunistic crimes.
