Charles Lane with some smart words on Rand Paul:
Suppose an African American customer sits down at a "whites only" restaurant and asks for dinner. The owner tells him to leave. The customer refuses and stays put. What are the owner's options at that point? He can forcibly remove the customer himself, but, as Paul concedes, that could expose the restaurateur to criminal or civil liability. So he'll have to call the cops. When they arrive, he'll have to explain his whites-only policy and ask them to remove the unwanted black man because he's violating it. But they can only do that on the basis of some law, presumably trespassing. In other words, the business owner's discriminatory edict is meaningless unless some public authority enforces it.Conversely, it is precisely because of this nexus between private discrimination and public enforcement that the larger community, through the political and judicial process, acquires a valid interest in legislating against discrimination. The public is entitled to say whether their tax money should pay for arresting black trespassers on whites-only property.
