In fact, the motorcylce policeman was urged to change his testimony for the WC (probably intimidated with a threat), I believe his first account, not the 2nd.
***Who says Oswald can't be placed in the crime scene? Oswald worked there. He was seen there. He admitted being there.***
“Taques book was interesting, not to mention that Oswald can not physically be placed in the crime scene, some of the earliest basic evidence provided by people in the depository and the motorcycle policeman show that.”
Myth. He was able to get to the break room from the sixth floor in time. This has been demonstrated by recreations.
He was working on that floor. There finger and palm prints on the rifle and the boxes that place him there.
The policeman didn't change his story in any way that would make a material difference.
