Connecticut's Bradley International Airport next week will become one of the first in the country to deploy passive screening devices that look for anomalies in body energy as passengers walk by. The portable devices, which work on millimeter-wave technology, can spot concealed weapons that alter a person's natural energy patterns. By positioning the devices around ticket counters and other areas, officials hope to prevent "the person with malicious intent from even getting to the security checkpoint ... It's a great additional layer of security for what we do," says Agustin Reyero, a TSA trainer.
