Why would a robber walk through the door and shoot someone immediately? If he had a weapon it would be reasonable to assume he would want to avoid using it unless necessary, and the teller was an idiot for giving him a reason to use it if he had one.
Yeah why would he use it immediately? If he wouldn't use it imemdiately, why is asking to see the weapon a reason to use it either? He wouldn't use it either if someone asked, its just the same thing. I don't think that qualifies as a reason to use one.
The teller did nothing wrong. If a police officer was in the bank at the same time and chased him down, he would be considered a hero, but this guy gets fucked over for it? Yeah I know, I'll get the canned "but police are trained" response, but no amount of training is going to stop a criminal from doing something crazy in those situations. Arguing against this guy running him down, you could make the same argument for police chasing any criminal down. Yet there's dangerous car chases every day.
I'm glad someone steps up to catch a criminal. He should be applauded, not reprimanded. All these 'what ifs' - yet no one got hurt, the bad guy got caught, the end. I'm sure he'll find another job, since this guy is probably a mini celebrity right now in his area, and a lot of people would like to have a guy who has the balls to step up and do something.
