Looks like there was someone there:
After all, when he realized there was an incident occurring at the Tucson Safeway supermarket Saturday where Congresswoman Gabrielle Giffords was holding a constituent event, Mr. Zamudio thought he could help, since he was legally carrying a 9 mm semiautomatic.
“If I’d gone down there sooner, maybe I could have shot him myself,” Mr. Zamudio, age 24, said in a phone interview Sunday night.
Mr. Zamudio, who works at a Tucson art gallery, was at a nearby Walgreen’s buying cigarettes when he heard the shots and immediately turned and ran toward the commotion. “In that moment, I didn’t think about it. I just reacted.”
He saw the blank face of the suspected shooter—”almost a smirk.”
By the time Mr. Zamudio was in close range, others had wrestled the suspect to the ground. Mr. Zamudio helped hold him down.
Didn’t quite get there in time. No doubt our opponents would say this was a dangerous individual trying to be a hero, and only would have racked up more bodies in his incompetence, but if one wants to be a hero by shooting someone who is actively murdering a crowd of people, including children, go right ahead.
