The film frame above is like an Escher's cube, also known as an Impossible Cube.
In it, the Curler Woman's right shoulder (in black) is in front of Lovelady's chest, obscuring it. At the same time, his head is in front of hers, partially obscuring it. So, they are both, in front of, and behind each other, at the same time.
It is a phony clip. It wasn't even seen until 1966, three years after the assassination. This film, like all the others, fell into government hands, but nobody noticed Lovelady until 1966? At the time, Harold Weisberg was making a stink that Lovelady wore a short-sleeved striped shirt, and to counter that, they came up with this clip. But, it's fake. Lovelady DID wear a short-sleeved striped shirt.
It was a lie; a government lie; a very elaborate government lie, which they went to a lot of trouble to make. Lovelady was not milling around outside the TSBD 15 minutes after the shooting. He was inside the building by then. Weren't all the employees?
This is 2015, and there is no excuse for anybody falling for this shit.
