An act requiring the Transportation Security Administration to establish pilot programs to develop and test new airport security systems at airports including Denver was signed into law July 15. The legislation, introduced by U.S. Sen. Cory Gardner, R-Colo., seeks to address short and long term concerns about security checkpoint lines using existing TSA resources and airport reimbursements. “The bill creates two pilot programs focused on increasing efficiency and security at airports and establishing prototypes for new and innovative screening techniques,” Gardner’s office said in a news release.
