Joe Zamudio had a gun himself and was prepared to defend himself and others if necessary, but decided to help take out Loughner with his bare hands.
Private citizens with guns are a thousand times more restrained in their use than the police.
Had Joe Zamudio been a statist enforcer, you can rest assured Loughner would have been shot dead.
Zamudio’s responses to the criminal statist Ed Schultz’s questions were so awesome that he deserves a medal just for the interview, let alone his heroic actions.
Zamudio makes it clear that had he been there when Loughner started shooting, the tragedy would have been averted… ummm rather quickly.
