Thursday, Thomas and another man with semiautomatic handguns entered the Waffle House in the 2900 block of Elysian Fields Avenue, police said. The other man jumped the counter and demanded money from the cashier, while also taking $8 from a costumer, according to an NOPD release Friday afternoon. Thomas stood on the side by the counter and served as lookout for the other man. A customer armed with his personal firearm drew his weapon as the other robber approached him, causing the robber to flee. Thomas then pointed his own weapon at the armed customer, the police release said. The customer fired several shots at Thomas, who then ran out of the Waffle House and fled in a white Chrysler with the other robber.

The target showed up at a hospital, later, wearing some new holes.

And as extraordinary and special as Mr. Shaw's actions were, what are the chances the Louisiana crime, with two armed perpetrators, could have been stopped by a single unarmed man?

I get the impression some people always picture criminals as cold blooded killers from some movie they saw.  From what I see looking at actual events, the first one who ran at the sight of a gun is more typical.
