Quote from saxon:
I saw a press conference with Gen. Michael Hayden last night (former head of the NSA) on the issue of communications intercepts. He made the case that, under the 4th amendment, all the president really has to do is show that what he ordered was 'reasonable'. Further, he said that the general guidelines for these intercepts are:
1) Communication must occur between a domestic and a foreign party...AND...there must be some connection to al-Queda.
2) If communications are inadvertently intercepted that do not meet condition 1, they must be expunged.
Take that with however many grains of salt you think appropriate...

Those guidelines were created by the President himself, in order to "expand" his authority, not expressly provided for by Congressional Act. This is just like when the IRS says that you're supposed to give them a "log" of your auto mileage to prove your deduction if audited. Congress didn't write that into the IRS code. It's an administrative regulation that expands on the statutory construction, because Congress delegates its legislative authority to the Executive Branch as necessary to implement Congress' legislative policy.
So, the head of the NSA, probably just wrote a rule to make it easier to comply with the statute.
HOWEVER, the FISA statute is pretty clear about what the requirements are for warrantless surveillance, unlike the IRS code and the auto mileage log book. The idea that all that's required is "reasonablness," is based on the premise that most administrative requests for court warrants, such as an FDA requested warrant to inspect a drug manufacturing plant, are based on a showing of a "general and neutral enforcement plan."
But, this is totally different. Here, the President is engaging in warrantless searches and seizures. The Fourth Amendment requires "probable cause," i.e., a fair probability that a crime has been committed, before a warrant can be issued, that warrant must be issued by a "neutral and detached magistrate," and any warrantless search, like a search of an auto, requires and exception, and there are no exceptions to electronic surveillance, except possibly (I'm thinking this through while I write it), that the government can assert that this is a "border search," if the calls are initiated by someone outside of the U.S.
Actually, this is a genuine exception, although, as far as I'm aware, it's never been applied to electronic communications. It is, however, fairly routinely used by U.S. Customs to authorize warrantless searches of persons who are crossing the border.
For example, a warrantless "body cavity" search can be conducted at the border, with only "reasonable, articulable facts suggesting that criminal activity is afoot."
So, this may well be a rationale that would work with a conservative Supreme Court, if it chose to back up the Pres.
The contra is that the Congress has created an express mechanism, and expressly stated that the warrantless electronic surveillance must NOT be of "U.S. persons." This argument is pretty persuasive to me, and I think that the Pres has overstepped his authority.
