Who is Lying?

South Dakota writes “Last week The Department of Justice claimed that it had not invoked Article 215 of the Patriot Act. (‘The number of times section 215 has been used to date is zero.‘) Yet in a year old USA Today news story it appears that hundreds of librarians told a University of Illinois survey that they had received FBI visits." The survey was also covered by Wired.

"Is someone lying or is there a loophole in the reporting system? What gives?" The ALA is also curious. I suspect things like arresting patrons and search warrants for library computers don’t qualify. Given the administration’s previously sanctioned use of false news information, the question "If these powers have been used, why are you lying to us now?" comes to mind.
