we will have on that panel, new york city counsel member david greenfield who has introduced a bill in. we're also joined by a staff member for congressman jason which many of you know as the person who sponsored the legislation that passed the house in 2009 to prohibt the -- prohibit the tsa from using scanners as the primary screening technique in the u.s. airports. although we have a brief break between 12:30 and 1:30, we'll be back after -- with a very good prosecution by bruce, and then a closing panel. if we could get underway, please, with our third panel. the bios are included in the speaker pact. they are available on the internet site, but it is a particular pleasure for me to be able to enter deuce our first -- introduce our first panelist, jeffrey rosen from the university school of law. i think among all of the people who have written and talked about the significance of surveillance, the human body, and privacy, there's probably no person whose written as broadly and as thoughtfully nor as with keen insight to what the direction the law might take us than professor rosen.
