More than two hundred years after the publication of his influential edition of Blackstone’s Commentaries, St. George Tucker, the distinguished Jeffersonian jurist, is at the center of controversy. Gun-rights advocates claim Tucker as their spiritual forebear, but opponents of this view argue that Tucker’s interpretation of the Second Amendment can not be pressed into service in the modern gun debate without doing great violence to his thinking. The stakes in this intellectual debate have been raised in the wake of the Supreme Court’s historic decision in District of Columbia v. Heller. In that decision, two very different interpretations of Tucker’s views of the Second Amendment were set out. Justice Scalia adopted the gun-rights view of Tucker and Justice Stevens took the opposing view. One of the central points of contention in this modern debate over Tucker arises from the learned judge’s earliest discussion of the Second Amendment in his unpublished law lectures.
