Thought this was interesting: VIDEO: Florida man armed with machete fends off robbers Please note one of the bad guys is armed with a pump-action shotgun, which he chases the victim with - and then retreats as the victim arms himself with a machete and comes out swinging. Seems to me he either didn't know how to use his weapon, it was non-functional (or empty) or he didn't want to pull the trigger and commit murder. But he clearly expected the gun to be a magic wand, as many people (good people and bad people) seem to do. They imagine if they just wave it around, everybody will do what they say to do. Doesn't always work that way. If you are not prepared to kill, waving a gun around is probably not that great of an idea. And sometimes it's a bad idea even if you are prepared to kill.
