He was well known for his fast driving and sharpshooting skills. He made such an impression that in 1930, he was handpicked to join a band of lawmen in Chicago who became known as The Untouchables. He was an expert at wire-tapping and Elliot Ness called him "a good man to have around when more than ordinary courage was needed."Paul spent his last years in Florida and was the last living of The Untouchables.
