Truster
The Israeli Mossad Security Service developed a top-secret new technology to interrogate suspected terrorists in the field. This technology is called Truster, a portable hand-held lie detector that fits right in your pocket. After a bombing, the Mossad would disperse through the crowd and ask bystanders if they knew anything about the attack. Measuring the level of stress in the subject's voice, Truster would immediately detect a lie, and the offender would be detained for questioning. The US National Security Agency and CIA purchased this same technology from the Israeli Army in 1999. US Government agents have been using it ever since in the war on terror. Detainees at Guantanamo Bay are even now being interrogated with Truster-like devices.
