From The Truth About Guns:

About a year ago, a man in Houston made an extremely dumb decision: to pull out a realistic looking but fake gun and rob people eating at a local taco restaurant. He didn’t know that one of the diners had a pistol, and the moment he turned his back to threaten other diners, he got a severe case of sudden onset lead poisoning.

The case was eventually submitted to a grand jury, who called for no charges against the man. So, the controversy over the number of shots and shooting after the robber was down, won’t be used against him in a trial, as there will be no criminal charges or a trial.
