That's all possible, Olivant. And Neri in his police mufti was the right ploy to get close to Barzini. But putting it all on him and his six shots left no margin for error. A carefully laid-out plan (i.e., not driven by directoral license) would have had backup shooters as pedestrians or in cars, if needed. Even a dunce like Gotti used multiple, identically clad shooters in the Castellano hit--and had himself and Da Bull in reserve in case needed.
