Is that Al Neri in the cop uniform at the courthouse where the driver, the bodyguard, and Barzini get hit?

Anyway, wasn't the hit on Barzini sloppy work? Almost unbelievably so?

Barzini gets shot at a distance from behind what, 3 times? Then the killer takes off, apparently assuming Barzini was dead?

Point: A competent and professional dago guinea wop goombah hood would have put a couple of shots in Barzini's head to be sure the work was done properly. Even taking the time to reload if necessary...

For that matter, Sollozzo's button men made the same (inexcusable and inexplicable) mistake when they hit Don Vito...
