Legal Debate on Terrorism Surveillance

The National Federalist Society has just put out a monograph on domestic surveillance and counter-terrorism, with both the ABA's take on what it (shockingly) considers the illegalities of these programs, and an alternate point of view. I've only had the chance to skim it, but it's very interesting stuff. Most of the other things I've seen so far, like Ranjit's nod to Orin Kerr, has focused on statutory concerns, but this looks like it addresses broader inherent power concerns.
