From USA Today:
The TSA lacked centralized controls over the secure passes issued to some of its employees, according to DHS Inspector General Richard Skinner. The passes grant people access to the most sensitive areas of an airport, such as where baggage is screened or planes are parked.
Investigators found numerous cases in which former employees retained their passes long after they had left the agency, and in which TSA uniforms were not collected when employees left or were transferred.
People using improper badges, IDs or uniforms — particularly in combination — “could significantly increase an airport’s vulnerability to unauthorized access and, potentially, a wide variety of terrorist and criminal acts,” the report said.
