On this edition of Hero of the Day, Cam Edwards shares a story from Ireland where homeowner Dan O'Sullivan, 55, was the subject of two home invasions. In the first, burglars were attempting to break down his door with a sledgehammer when he stuck his shotgun through the mail slot and caused them to flee. The police came and confiscated O'Sullivan's shotgun. The second incident happened a few days later when O'Sullivan heard his window break. He loaded a friend's shotgun and fired a warning shot, causing the criminals to flee again. O'Sullivan's friend's gun was also confiscated. Originally aired 6/3/2011.
