Metaphors and the Constitution: Wiretapping as Search

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated; and no Warrants shall issue, but upon probable cause, supported by Oath or af´Čürmation, and particularly describing the place to be searched, and the persons or things to be seized. (US Constitution, Amendment IV)

The controversy over NSA wiretapping involves two different legal issues. One is whether the actions are illegal, the other whether they are unconstitutional--whether a statute permitting them would be in violation of the Fourth Amendment. A group of legal professionals ranging from Richard Epstein to Lawrence Tribe have produced a summary of the arguments against the administration's position on both issues. In my view and theirs, the illegality of the actions is clear. They think the actions are also unconstitutional; I am less sure.

The Constitution says nothing at all about wiretapping. It says nothing about eavesdropping on conversations, which might seem the closest equivalent given 18th century technology. What it regulates are searches. Past court decisions have treated wiretaps as searches and so required warrants for them. But a wiretap is only a metaphorical search--it differs from a literal search in important ways, some of which raise problems for interpreting the Consitutional restrictions.

Suppose George has been having a possibly criminal correspondence with Thomas. The government gets evidence against George, obtains a search warrant, searches his house and finds letters from Thomas and drafts of letters to Thomas. They have obtained information about both George and Thomas, but they only needed a warrant against George, since only his house was searched.

Now fast forward a few hundred years. The government gets a warrant to tap Bill's phone--but what they are actually "searching" is not Bill's house but his conversations with George. Still legal--but the distinction between searching Bill and searching George has vanished.

Finally, consider a conversation between George and Usamah. Usamah is not an American, so the government is, constitutionally speaking, free to tap his phone without a warrant. But George is an American person--and they are listening to his conversation too. Do they need a warrant? Under the terms of FISA they do--but is that a constitutional requirement, or only a statutory one? Is the wiretap equivalent to searching both houses, or to searching Usamah's house and finding letters from George?

If the bill of rights is an enumeration of rights that the people (i.e., the citizens) retain, then your statement follows directly. OTOH, if it's a list of further restrictions on government power over and above the enumeration of powers in artcle 1 sec 8, then it's not clear why these restrictions would not apply even in dealings with foreign nationals.

What about the 10th amendment?

The bill of rights weren't intended be the list of all rights. In fact, one argument against the bill of rights was that it would be used to limit peoples rights, hence the 10th amendment.

What role do you think the 10th amendment plays in this case?

David raises an important distinction. People often confuse "illegal" behavior with "unconstitutional" behavior, when they are not necessarily one and the same.

But for determining the provisions concerning indictment or impeachment, the distinction is irrelevant. If Bush et al's actions broke the FISA law, that would certainly satisfy a "high crimes and misdemeanors" provision. He could argue the "constitutionality" of his actions as a defense (as Nixon infamously did), but the case of statutory illegality seems rather cut and dried, imo.

Thank you for writing on this subject, I am in a class on government, and we are talking about wiretapping today as a debate project.

I will link to you in my blog on blogger, and I am letting you know.

Thanks, again,

P.S. I will post a reply with my thoughts on the matter soon.
