If you think of American conservatism in rigidly ideological terms, such enthusiastic responses might come as a surprise: Conservatism, we are often told, means limited government. The overbearing, omnicompetent state easily becomes a tool of tyranny. If unchecked, the road to serfdom — the premises that, as Friedrich Hayek argued in his 1944 book of that name, economic planning creates the underlying forces for totalitarianism — is a short one. Or so the argument goes. But if conservatives really believe this is the case, why do so many of them reflexively defend the police, the armed servants of the state?
