How does the old saying go?

...the best thing to stop an armed bad guy is an armed good guy?

A pawn shop worker fatally shot a 50-year-old customer after the man loaded a handgun from the case with his own ammo, left the store and fired a round at the employee.
The Houston Chronicle reported Sunday that Melvin Clark, a regular customer entered Northwest Pawn Shop on Saturday afternoon and asked to see a pistol. Clark loaded his own ammo into the weapon with the store employee's approval.
Clark left the store, turned and fired at the employee. Officials say the employee returned fire, killing Clark.

So much for the anti-gunners' contention that if the bad guy pulls his gun first the good guys might as well not even be armed. And how about that headline? 'Pawn shop worker kills customer'? No bias there, no sir.
