Using realistic reenactments, crime scene and courtroom footage, and interviews with police personnel and research scientists, this program showcases 21st-century advances in law enforcement. On the technological side, an array of nonlethal weaponry, including the Laser Dazzler and the TASER, and a computer program that can analyze videotaped faces to determine if the people filmed were lying are featured. On the tactical side, high-tech training on virtual obstacle courses, techniques used in high-speed pursuits, and the application of neurolinguistics to determine if drivers who have been pulled over have something to hide are spotlighted.
