ABSTRACT
This chapter addresses an empirical basis the effects of the use of metal detectors as a security initiative at airports and describes primarily, crimes against aircraft and airports. Attacks at airports serving international civil aviation and at other aviation facilities have also been a major terrorist strategy and prediction problem has caused deaths, and property damages. The new Tokyo International Airport has been a target of attacks and explosions and most of the incidents resulted in deaths, injuries and destruction of airport property. Profiling, identification cards, and body searches were implemented in many airports. However, a problem caused by the model was that metal detectors were not introduced in all airports around the world at the same time, and there are problems related to the accuracy of the data. The data needed to analyse a legal problem or system should be defined quite directly by the model that is designed to handle the prediction problem.
