Orin knows this body of law much, much better than I do, and I take his word for it. It encapsulates, I think, much of what irks me about 4th Amendment law. The quotations Orin includes from the cases upholding this practice against 4th Amendment challenges say what much 4th Amendment jurisprudence says: the government cannot “seize” me unless it has a good reason (or maybe even a damned good reason) for doing so. Not comforting. I recognize that the source of the problem is in the Constitutional language itself – which declares, of course, that we don’t have a right to be free from searches and seizures, we have a right to be free only from “unreasonable” searches and seizures, and a reasonableness test will, inevitably, become an open door; if the First Amendment protected only against “unreasonable” abridgements of the freedom of speech, we would’ve gone to hell in a handbasket on that front a long time ago.
Orin did acknowledge that “some readers will contend that the cases are irrelevant to what the law truly is. If the cases say that, they will reason, then it just shows how the judges don’t understand what the Constitution truly means.” Count me among them.
