An incident caught on film in the city of Campinas, Sao Paulo, Brazil, is sure to make your heart stop. On Tuesday, an off-duty cop gathered with his family in what looks to be a fairly quiet area. As he stood holding his three-month-old daughter, a robber approached the group and brandished a submachine gun. The father was quick to act. He dropped his infant daughter and fought off the convicted criminal trying to rob his family. Luckily, the little girl suffered only minor injuries from the fall.
