the restaurant scene
Why didn’t the Corleone’s just have a couple of button men in Louey’s restaurant once they found out the meeting would be held there? That way, there’d be no need for Michael to be directly involved in the shooting.
My only guess is that because it’s a family restaurant, a couple of mob hitters sitting there might have aroused Solozzo’s suspicion when they entered....but maybe they could have had a couple of girls with them to make it look less obvious
The only other possibility I can think of is that Michael WANTED to take care of it personally. It’s funny that it wasn’t even suggested though (when they were suggesting other things like putting a tail on the vehicle or just shooting the car when it arrives)
