There is a lot more that makes no sense at all. If Oswald was the assassin and he managed to get down to the 2nd floor, why not simply turn right, walk through the office space and out of the building? Why stop in the 2nd floor lunchroom?
Yes, Martin. Exactly and beautifully said. I know I sometimes use comparisons of other crimes to make a point. But it'd be like Tim McVeigh parking the van full of explosives next to the building in OKC, then going into the actual building to buy a soft drink in there, drinking it, perhaps then go into the restroom to take a xxxx, and then KABOOM!
I'm joking, of course, but the logic for Oswald's so-called actions make no sense that day. Another one - the getting on the bus, getting out and starting to get into a cab but letting a lady take that cab first are not the actions of a so-called madman who supposedly just murdered the president.
And another one - as he returns to his rooming house and decides to go see a picture show, he somehow takes a very long roundabout way to the theater, where he supposedly runs into Tippit and murders him. All he'd have to have done is walk straight down the street from his rooming house and turn right to the movie house.
