The question raised is whether this machine can detect explosives hidden in private areas. Some of the passengers strictly object to the pat downs in addition to the WBI scan as the agent has to come in intimate contact with the passenger.
After the heartening incident of 9/11, there were several short term regulations introduced but the more important ones were the long term changes. Immediate consequence was the background check of more than 750 000 airport employees, placement of a larger number of investigative staff, extensive search and scanning of all the checked baggage. Under the more long term effects, the passengers are now more closely restricted to the amount of baggage and hand carry they can take with them. Addition of new agencies to overlook the security enhancements was inevitable. As much as the vehicles arriving at the airport are meticulously checked and rechecked, no matter if they are to see the passengers off or to receive them. The security systems are proving to be costly in Japan. As they have privately owned security companies, it is getting difficult for them to afford such a high cost flight. Every year advanced technology is introduced to avoid such attacks, and it is getting more difficult every year for passengers to travel confidently. They get conscious about carrying things with them. These security measures are getting on nerves of passengers, but they are the things which have to be looked after. Entire crews of airports are highly trained and strictly ordered to take actions against any kind misbehavior or suspicion.
