How the D.C. v. Heller decision reflects on the idea of "natural law." Dave Kopel, research director at the Colorado Independence Institute, joins Cam Edwards at the 2009 Annual Meetings in Phoenix, Arizona to discuss his upcoming speech at the NRA Firearms Law Seminar. Kopel will be addressing the Heller decision in terms of what it means toward understanding the Founding Fathers' concepts of "natural law." "Natural law," according to Kopel, is the idea that there are "natural, obvious principles of justice" that are inborn into the world. It is the meaning behind "we hold these truths to be self-evident" in the Bill of Rights.
