the subject of this topic has always bothered me. vito is always seen as this wise and street-hardened don who's been through everything and has seen it all. the move he makes by sending luca to tattaglia and sollozo is something fredo wouldn't even be stupid enough to attempt. think about it. vito has just turned down sollozo and tattaglia's offer to cover for his drug business, so it's not like they're on the best of terms. now all of a sudden luca brasi, who's been don corleone's most fierce and loyal killer for many years, is unhappy with the corleone family and wants to join the people who vito just turned down. until sollozo approached the corleones no one is the family had ever heard of him, now all of a sudden the right-hand man wants to join forces. did vito honestly expect them to just welcome luca in with open arms? even if they didn't kill him and let him into the family, i'm sure they would have kept extremely close tabs on him for quite some time just to be sure he truly was out of the corleone family, so how's he supposed to get in touch with any corleone men? my guess is when vito and michael died, they went straight to hell and had to suffer for all eternity by having luca and rocco shove large, cumbersome objects up their ass for sending them on suicide missions.
