Held on April 28 at the University of Colorado law school, under the sponsorship of the American Civil Liberties Union of Colorado. Arguing in favor of constitutionality was Jean Dubofsky, former Justice of the Colorado Supreme Court. Arguing the other side was me. The video is here. (Video and audio are often out of sync by several seconds.) The format was Kopel presentation, Dubofsky presentation, Kopel rebuttal, Dubofsky rebuttal, and then questions from the audience. Pursuant to the framing of the question, both of us devoted substantial attention to whether Colorado Attorney General John Suthers made the right decision in joining the 20-state coalition lawsuit against the new law. The pro/con presentations take about an hour, and the full program is 1 hour and 36 minutes.
