The Bronson film is inconclusive. Hickey's attorneys were trying anything to help their case. By all accounts, Donahue wanted to find evidence that Hickey didn't fire the AR-15, he would have welcomed the Bronson film if there was anything to it that could be pinned down.

so tell me in which of those frames is there a guy standing up tall enough in a limo to get a weapon raised high enough to shoot over the windshield?
and in all of the lunatic nonsense that people claim they saw in the plaza that day...why hasn’t there ever been one person say they saw this happen? People were 15 freaking feet away and a guy stands up in the back of the car, tall enough to clear the windshield and blasts off an AR-15? No one notices? not one witness? Not Bill and Gayle Newman? what were they 10 feet away? they didn’t see a guy stand up and shoot off a gun? really....
pure bunk ...all of it
First, this does not deal with the “Mortal Error” theory but in general about the assassination.
Previously, I had not seen this photo on the right, rather than cut and paste the whole big thing, I will just link it:

Side by side two pictures of that grassy knoll area at the same time.
This is from a book by the author Groden.
