The route was reported to have been changed and evidence was presented that Oswald was not aware of the route. These are ‘reasonable’ points for consideration. They are not conclusive just as your point references are not conclusive.
Ok, that’s all we are going to exchange for now. Anything further is a waste.
Wait, you're actually sticking with that nobody knew Kennedy was actually coming!?
Again, where did the crowd come from?
It was the usual parade route. Nothing changed.
