I just stumbled across this on the TSA website:
http://www.tsa.gov/assets/pdf/foia/t...y_03162010.pdf
It is a 451-page long PDF file containing complaints that TSA has received about the nude-o-scopes. Apparently it is a response to a FOIA (Freedom of Information Act) request.
(Moderators - apologies if this is a dupe. I searched FT for the URL, but didn't find it.)
