Pretty hard to gauge weight and height when you're witnessing such a traumatic thing and the subject is in a window.
Oswald did change his position, for a "kill shot" to the head. Real humanitarian, that guy you're trying to exonerate.
Not based on Tatum. If tTippit's killer stayed on the passenger side of the car and Tippit was still alive laying on the pavement by the driver's door, did the gunman fired the fatal shot through the engine?
Plus read calanans testimony. He says there was a delay before the last shot was fired. This matches Tatum's testimony.
Who?
