Recent nemesis Glenn Greenwald has uncovered some interesting facts.

On June 20, 2002, Republican Senator DeWine of Ohio introduced legislation (S. 2659) that proposed substituting “reasonable suspicion” for “probable cause” as the standard for obtaining a FISA warrant. This was to pertain to cases involving non-United States persons only. Such persons would presumably account for an overwhelming majority of requests for a FISA warrant.

The context for this proposed legislation, which did not become law, is the speech delivered by General Hayden yesterday, in which he said

    The trigger is quicker and a bit softer, but the intrusion into privacy is also limited: only international calls and only those we have a reasonable basis to believe involve Al Qaeda or one of its affiliates. [emphasis added]

In my mind, “reasonable suspicion” and “reasonable basis to believe” are synonymous.

[UPDATE. The full text of Hayden’s speech is here]

I agree with Greenwald that the Administration should have welcomed the proposed change to FISA. But it didn’t. Here’s an excerpt from the statement submitted by James A. Baker, the Justice Department lawyer who oversees that DoJ’s Office of Intelligence Policy and Review, which is the group that “prepares and presents all applications for electronic surveillance and physical search under the Act to the Foreign Intelligence Surveillance Court (FISA Court or Court)”:

    The Department of Justice has been studying Sen. DeWine’s proposed legislation. Because the proposed change raises both significant legal and practical issues, the Administration at this time is not prepared to support it. [emphasis added]

What were these issues, and why did they prevent the Administration from supporting the proposed legislation?
