The TSA has used a "Privacy Impact Assessment Update" to announce an unlawful procedure for screening air travelers in the United States. The agency claims that it may "mandate body scanner screening for some passengers." In EPIC v. DHS (Suspension of Body Scanner Program, the D.C. Circuit Court of Appeals ruled that the screening was Constitutional because passengers could always opt out. As Judge Ginsburg explained, "any passenger may opt-out of AIT screening in favor of a patdown, which allows him to decide which of the two options for detecting a concealed, nonmetallic weapon or explosive is least invasive. "The TSA has also failed to "act promptly," as the Court mandated, to finalize the legal authority for the program.
