Witnesses recall Waukesha Christmas parade tragedy

An SUV driver sped through a police line and into a parade of Christmas marchers on Sunday, hitting more than 20 adults and children. One video shows a woman screaming, “Oh my God!” repeatedly after a group of girls wearing Santa hats and dancing with white pompoms is struck. Another shows the SUV plowing into members of a marching band, their music replaced with terrified screams.
