The Federalist Society's annual conference in Washington, D.C., opens on Thursday, November 20. The evening before, the Mason Law Federalist Society and American Constitution Society are co-hosting a symposium on D.C. v. Heller. The events takes place from 5-8 p.m. at GMU Law School, in Arlington, Virgnia. Speakers include Steve Halbrook, Nelson Lund, Clark Neily, John Frazer, and me, on the side of the Standard Model, and Alan Morrison, Dennis Henigan, and others, on the opposite side. My presentation, in the panel "Looking Back at the History of the 2nd Amendment," will be about the natural law roots of the Second Amendment; it's the topic of my forthcoming article in the Syracuse Law Review. The event is free, although if you want the 3 CLE credits, there is a $25 fee. Registration is here.
