Perfect. The police rush in and there is one bad guy with a gun and one good guy with a gun.
As they point at each other: "He's the bad guy!". Or the scenario one bad guy with a gun, telling a good guy with a gun, that another good guy with a gun is really the bad guy. Then they shoot each other before the cops arrive. Along with a few shoppers participating in a 2 for 1 sale. "Store associate, cleanup in the can goods aisle". With the so called bad guy grabbing a steak on the way out the back door.
Of course the first cop to respond was also shot, and killed. As if his training was less than that of a civilian.
