This is the one (Limo speed) that I havent heard explained...and until I do, to me it is cause for question and considering that on its face it would appear completely improper to the point of incompetence (something that does not exist in the Presidential detail for the President of the United States) gives me cause for concern...enough to say something was fishy.
And until that is addressed I cannot say that this whole scenario has just been manufactured by theorists.
