On this edition of Hero of the Day, Cam Edwards shares a story from Pensacola, Florida where Jack Crawford, 72, answered a strange knock at the door armed with his legally owned handgun. Immediately after he opened it, one of three teenaged boys on his doorstep hit him in the head with a baseball bat. Crawford shot two of them and the other fled. After treatment at the hospital, Earl Benard, 15, Nathaniel Nichols, 17, and Curtis Crenshaw, 18, have been charged with home-invasion robbery and aggravated battery in connection with the case. Crawford recovered from his head wound and has returned home. Originally aired 1/31/2011.
