A popular video "How To Get Anything Through TSA Nude Body Scanners" show that it is easy to bypass airport body scanners by hiding materials perpendicular to the plane of the scanning devices. The video also notes that traditional metal detectors, now being removed from US airports, would routinely alert to the presence of metallic objects. Still more interesting may be the recent blog post by a 25-year FBI agent, expert in aviation security, who writes that the "TSA has never foiled a terrorist plot or stopped an attack on an airliner" and that "the entire TSA paradigm is flawed." In a federal lawsuit, EPIC challenged the TSA airport scanner program, calling it "invasive, unlawful, and ineffective." For more information, see EPIC v. DHS (Suspension of body scanners).
