Ben Miller: Frontier Doofus
Sure, Ben, make a racket by smashing in a glass window for a stupid hat. True, the Miller gang couldn't have known Kane was just around the corner, but in that quiet, knowing their intended victim was probably in ear-shot, it was a really dumb movie. And he paid the price for his goofiness.
His window-smashing was almost as dumb as Kane walking right into a showdown with four dangerous gunmen out to kill him, and going armed only with pistols--when his office seemed to have a nice collection of shotguns and rifles--and not really much of a strategy.
