Supreme Court Justice Antonin Scalia, who died Saturday at the age of 79, had a way with words. In court, those words weren't so much spoken as thundered. And in his memorable dissents or important majority decisions, those words could often be described as biting. The Catholic, Italian-American justice, the longest-serving on the court, was passionate about his belief in the Constitution and his faith. "He was a hysteric in cases he cared about most," legal scholar Cass Sunstein told NPR.
