That whole scene was filmed for dramatic effects, not for logic:
--Two gunmen armed with submachineguns to kill Tattaglia and the hooker he was in bed with?
--Neri takes out Barzini and company with a single .38 revolver?
--Fat Clemenza climbs all those stairs to intercept an elevator car? In that confined space, none of the three (including the operator) would have survived two shotgun blasts.


Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
