I have been wondering about this and the N Hollywood robbery.
It is pretty easy to armchair each one, and necessary, though the boys had to deal with the situation as it faced them, with what they brought to the table.
Each reacts to the situation before them differently. Sometimes training and tactics are better used, Hollywood IMO, but often the situation is so quickly thrust on one that the first reactions determine the outcome, without benefit of time to think.
Training goes a long, long way, that said, mind-set and disposition at the actual moment are factors which cannot be pre-determined, or, what we will actually do is different from episode to episode.
It is always good to have enough firepower at the beginning because both episodes showed that there is precious little time to deploy different armament.
The choices of weapons in both situations proved that being undergunned is a bad decision and I have never seen a situation where the winner said I wish I had used a lesser caliber.
