Matt Blaze, and several other distinguished persons, appeared before the House Committee looking at the FBI's Carnivore system for hoovering email and a copy of his written statements (with Steve Bellovin listed as co-author), as reportedly favorably by the news folks at 'Good Morning Silicon Valley', is available at: http://www.house.gov/judiciary/blaz0724.htm The Committee meeting was carried by CSPAN-2 on cable TV (at least in my area) and may be repeated again so check your local listings.
