I’m a physicist by training and by vocation too, and if you have even been to Dallas, and seen where the deed was done..... It was like shooting fish in a barrel. Oswald couldn’t miss if he had any skills. They didn’t need to be very developed. Just a rudimentary ability to aim and squeeze the trigger.
Oswald could easily have gotten off three shots in the time allotted.
It’s one of those things that the Zapruter film just doesn’t give, the sense of how small the area really is. You watch the film and you think it was a conspiracy. Then you go there and you look at the area, and you realize; how is it possible for him to even miss.
The act has never been duplicated. That is a fact.
It WAS like shooting fish in a barrel to the 2 or 3 shooters in the area, including the one who missed and hit the pavement and curb, and the one who missed and hit the man standing under the overpass, but not to Oswald, who didn't fire a shot.
I've seen the recreations on TV- they are what we physicists technically call “bull$hit”
