Today the White House formally released the names of the committee of "outside experts" to review the NSA's surveillance practices. A fifth name was added to the list beyond the four leaked last week: Professor Geoffrey Stone of the University of Chicago Law School. I debated Professor Stone on national security surveillance issues back in 2005 or 2006 for a U of C Federalist Society event. Based on that experience, my sense is that he will come at the issues from a strong civil libertarian perspective, with the caveat that he is not a subject matter expert in surveillance law or technology. Stone is the author of the book Top Secret: When Our Government Keeps Us in the Dark.
