"...How did that shooter get so close to him in a police station?..."
Apparently, he was quite chummy with the police. According to Buglosi (and apparently, the Warren Commission) Ruby was a frequent visitor to the inside of the Police station on a social basis. He purchased a stack of ten Pastrami sandwiches to bring down to the station that day, and just walked in. they all knew him. He apparently would go down there and give the cops free passes to his clubs...
He tried to go into the room where Oswald was being interogated (tried the doorknob) and a couple of the detectives stopped him and said something like "Jack, you can't go in there..." but they didn't kick him out.
Sounds like they all knew him.
Your post really gives me no new information.
You are exactly correct though.
I have always been troubled by the FACT that the Dallas Police Department did not see fit to raise their level of vigilance in late November 1963.
Now this image below...that one gives me the creeps. Never mind the autopsy photos, which I have seen a few of.
Congressman Albert Thomas.....winking to LBJ on board Air Force 1, with the dead President below, and the just former (a few minutes ago) First Lady just beside.....
