Preventing terror attacks and crimes against our citizens has become a vital security concern for our country and our allies. Fundamentalist ideologies have threatened our national security. Terror groups have had access to hazardous materials using them in non-conventional and suicidal terrorist acts. Conventional searches for concealed weapons, explosives and classified materials is no longer sufficient. National infra-structures, including airports, sea and land ports, mass transit systems, high security facilities, nuclear power plants, prisons, and secured government buildings are vulnerable targets for terrorists and criminal attacks. Using today’s methods of fingerprinting, identity verification, background checks, and body scans, we are still unable to detect if a person has been compromised. GK1
