Open your eyes and LOOK .....Starting at the 9:52 point in the you tube video ....... Do you see Roger Craig " NOT MORE THAN SIX or EIGHT INCHES FROM THE RIFLE" and looking at the rifle??
a) a rifle isn’t even visible in the film segment that focuses on a man that the maker of the YouTube video is apparently identifying as Craig by circling his face in a blue tint.
b) why do you keep assuming that the extant Alyea film captured everything that happened with a rifle or rifles on the sixth floor that afternoon?
