First of all, the shot or shots were pretty remarkable, not necessarily for the accuracy but the speed in which they were fired.
Also having a Mafia character shoot the shooter was something right out of the movies.
I would bet the Mafia, Cubans, or KGB. My money would be on Castro and the Mafia.
“First of all, the shot or shots were pretty remarkable, not necessarily for the accuracy but the speed in which they were fired.”
Two shots in more than five seconds? Big deal.
“Also having a Mafia character shoot the shooter was something right out of the movies.”
He wasn’t a mafia character. Mafiosos don’t live in bubbles; they have to run into people who have no connection to the underworld every once in a while.
Anyway, if the movie was about a conspiracy, I’d question the logic of a plot that has Ruby shooting Oswald after he’d been in police custody for two days, plenty long enough to spill the beans. If it was a movie about an emotionally disturbed fellow who struck out in vengance for a fallen hero, I’d say it was melodramatic but effective.
