HR 2200, the Transportation Security Administration Authorization Act, was referred this past 8 June to the Committee on Commerce, Science, and Transportation, on which you sit. HR 2200 in the form in which it was received by your committee from the House of Representatives contains H.Amdt. 172 which would prohibit the TSA from using whole-body imaging for primary screening at airports, and would require the TSA to give passengers the option of a pat-down search in lieu of going through a WBI machine. The amendment also prohibits the TSA from storing, transferring, or copying any images of passengers that are produced by a whole-body machine. The need to preserve this amendment in the Senate mark-up of this bill has been demonstrated recently with an admission by the US Marshals Service, prompted by a Freedom of Information Act request by the Electronic Privacy Information Center, that more than 35,000 whole-body nude images from scanners at the Orlando Federal Courthouse secretly stored. This admission prompted a 19 August letter (http://politechbot.com/docs/lieberman.collins.marshals.body.scanning.081910.txt) from Senators Lieberman, Collins, Akaka, Carper, Chambliss and Isakson to Marshals Service director John F Clark, demanding an explanation and further details. As their letter points out, automated algorithms rather than humans can flag apparent anomalies in these scans, obviating the need for human inspection of these very revealing images. I urge you, therefore, to support this particular aspect of HR 2200 in its current form. With a seat on the Commerce Committee, you have great influence on the mark-up of HR 2200. Don't let that influence go to waste.
