Not really the best argument for gun carrying citizens are a good thing. If this was a gunman being taken down by another gunman, that'd be one thing. But since the crazy guy had a knife, the citizen could literally walk to within 4 or 5 feet of him and shoot him point blank. Going up against someone else with a gun, not a chance in hell would he be able to be in such control. It'd be a lot more random gunfire going on, since I'd assume the citizen would (wisely) take cover rather than simply going up to the crazy and shooting him.
