The pain is so great that people flee immediately. "It just feels like your skin is on fire," said Rich Garcia, a spokesman for the laboratory who, as a test subject, has felt the Active Denial System's heat. "When you get out of the path of the beam, or shut off the beam, everything goes back to normal. There's no residual pain." Yikes!
