Jan 3, 2011 — In an official TSA blog post last Friday (12/31), the TSA took steps to clarify some misinformation in the media about a "recent" report citing a 70 percent failure rate for TSA to detect guns and knives passing through airport checkpoints. Among other misreported details is the fact the "recent" report was about testing conducted in 2004-2005.
