A Massachusetts news reporter is being praised for nabbing a suspected dog thief as the cameras were rolling. Juliana Mazza of WHDH-TV was reporting the story of a stolen 13-month-old pointer named Titus — a crime caught on surveillance cameras in a Cambridge parking lot. Suddenly, Mazza saw Titus walking with a man and motioned to her cameraman to start recording. The man seemed befuddled after Mazza started questioning him. She called 911 and he was arrested.
