While I love Clint, and I enjoy his personification of Harry Callahan, while it was done for dramatic effect, adding to Harry's "coolness" and "swag", there's no way in Hell thugs, in modern day, would have even allowed him to reach into his jacket, maybe not even speak. They would have shot him dead. Heck, even those thugs back then, would have probably shot him dead.
Maybe it's me, I like the scene, full of action; a bit ironic of how brothers decide to rob a diner during breakfast and get taken down easily by the man with the big gun. The first time watching that scene really made my day, week, etc...lol
