Burns and his team of scientists are researching whether video game boards, biometric sensors and other high-tech devices can be used to detect distinct nonverbal cues from people who harbor "mal-intent," or malicious intent.
"We're looking pre-event," said Burns, the No. 2 at the Homeland Security Advanced Research Project Agency, a counterpart of the fabled Pentagon agency that developed Stealth aircraft and the Internet.
"We're trying to detect a crime before it has occurred.""
