There is one thing which bugged me about his capture. He was caught after the cops followed a white plastic bag which left his wife's house, in Corleone, was passed between a multitude of people, and ended up being taken to his hideout, thus giving him away.
So why did they not change the bag? This strikes me as being a very simple, not to mention obvious, precaution to take.
