I won't take Mr. Karnick on when film is the issue, but public policy is a different matter. The drinking and driving laws, it seems to me, are a very good idea and make a lot of sense once you accept the parameters of government in our society. Who finances the roads upon which we drive? Answer: federal, state, and local governments. May they attach conditions, particularly those that bear directly upon safety concerns, to the use of those roads? I would have to say yes. Drunk driving can result in the imposition of massive negative externalities upon other people and the state. The ultimate negative externality would be, of course, death. Other possibilities include damage of others' property, damage of state property, creation of massive traffic jams, lost time, lost wages, diversion of public emergency vehicles and personnel from other potentially pressing situations, etc. In my view, the implementation of strong public disincentives against drunk driving seem eminently reasonable. Cato Institute types, bring rain upon my head!
