Roger Craig was interviewed in 1968 and in that interview, he stated that Tippit was shot around 1:40. He was immediately corrected by Penn Jones, who told him (Craig) that the Warren Commission determined that the shooting occurred around 1:15. Craig's response to that? "Was it? Oh, that's right."
Then, a few years later, in the early 70's, while writing his manuscript "When They Kill A President", Craig states matter-of-factly that he heard about the shooting over in Oak Cliff on a nearby police radio while he was in Dealey Plaza and he looked down at his watch and noted that the time was 1:06.
Isn't it something that Craig didn't remember this 1:06 police radio stuff while doing the 1968 interview a few years earlier?
Think about it.
