Over at Cato Unbound, Bob Levy (Cato), Dennis Henigan (Brady Center), and I are debating the Heller case. All three of us have new essays on the subject. My essay published today looks at the fatal flaw in the Stevens dissent: its treatment of "the" in "the right to keep and bear arms." The essay also examines which types of gun bans and gun storage laws may now be unconstitutional. Erwin Chemerinsky will weigh in next week. Thereafter, we will engage in a four-way blog discussion.
