David Frum: Even when people violate legal norms that everybody knows the police won't respond to, at least for a while, there's often still a sense that those are violations of legal norms. He says we can all even kind of see it's a spectrum. There's some law that's always enforced with complete accuracy and others where you've got like an 80% shot. Frum: I want to now take our very philosophical conversation about common good constitutionalism and then jurisprudence and international law.
