OIG-08-25 – Audit of Airport Passenger and Checked Baggage Screening Performance (Unclassified Summary), February 2008 (PDF, 8 pages): “The number of tests conducted, the names of the airports tested, and the quantitative and qualitative results of our testing are classified. We have shared that information with the Department, the Transportation Security Administration, and appropriate congressional committees. As a result of our testing, we made six recommendations to TSA, which concurred with all of them. When fully implemented, these recommendations will improve an already strong passenger and checked baggage screening process.”
