The question of whether or not a brave person with a concealed weapon could have stopped the slaughter remains unanswered. Wiegel spoke to Greg Block, a California-based firearms safety trainer:
Holmes acted while a loud movie was playing in a dark theater. That, said Block could be "a great diversion" for someone trying to drop down and shoot back. But the "tear gas" -- we're still trying to figure out what kind -- absolutely gave Holmes the advantage. "All that's going to do is make people fish in a barrel," said Block. "Smoke would disorientate people. They may not even see the aisles." Any panic or movement from other people in the seats would be distracting, too. "But anybody from the military would hit the deck. They'd prone themselves between the chairs. That's how they're trained."
