This paper describes how, taken together, it is believed that the combination of understanding real science and putting it together with real-world context and observations and experience of the security expert can provide a very useful tool for the identification of those with hostile intent. Like all security screening techniques, it is not foolproof. At the very least, it has the advantage of informing those with hostile intent that specific security personnel are devoted to catching them, and ideally, that will dissuade the malevolent from attempting a hostile act in the first place.
