How Close Is Too Close?
The “good guy” with the gun against the “bad guy” with the knife (or machete, axe, club, tire-iron, etc.). “No contest”, you say. “The man with the gun can’t lose.” Or can he? A great deal depends on his ability with that gun and the proximity of his opponent.
If, for example, our hero shoots his would-be attacker at a distance of 20 yards, he loses. Not the fight, you understand, but most probably his freedom because he will almost certainly be charged with murder. The only thing that justifies your shooting another human being is the immediate need to stop him from trying to kill you (or someone else), remember?
