Oh, yes you did. I only wrote, "parade speed," and attached the value of 15mph, which is what Greer testified to and is supported by film of other motorcades. You decided that I musta meant some kind of "protocol." And then you demanded proof of a "protocol" that I never claimed.
Again, ~15mph (I'll put in a tilde to clairify this time) is the speed attested to by Greer and supported by film of other motorcades. The important part is that it's so slow that the turns wouldn't in themselves significantly affect the limos speed, if they slowed it down at all.
The whole trip downtown wasn't needed, either. As I've said elsewhere, if the priority was to minimize the President's exposure, they would have avoided the CBD and taken Westbound Mockingbird to Hairy Heiney and thence directly to the Trade Mart.
What Greer testified to doesn't mean that this is correct. Greer should have accelerated upon hearing the first shot, but he didn't. Greer should NOT have slowed to either a near stop or a stop, but he did. He is hardly a reliable source for this topic.
Stop trying to take attention from the fact that those two turns were NOT needed and were only added to make the killing of JFK much easier. LHO could not add the UNNECESSARY turns.
