TSA expands Pre-Check program

“This system enables our officers to expedite the screening process for passengers we know the most about, while better focusing their efforts on higher-risk and unknown passengers," he continued. "As we continue to implement a system with multiple layers of security to keep the traveling public safe, we are dedicated to providing the most effective security in the most efficient way.”

Pistole has testified recently before Congress that Pre-Check and other risk-based programs like its behavior detection plans would improve passengers' travels experience. The agency has recently announced it would  reduce controversial pat-downs for children 12 years and under and eliminate specific images of passengers being scanned.
