What does hijacker wants: How security forces negotiate with terrorists?
That is why the art of such negotiations has its own subtleties and stages, ignorance of which will certainly entail sacrifices. For example, having heard the demands of a terrorist, a common man in the street will draw conclusions about his ambitions and psychological state, while for professional negotiators, his demands become the key to resolving the situation.
The first thing law enforcement officers should do in such a situation is to make a clear distinction between instrumental and expressive motivation. If terrorists take hostages, seize buildings or kidnap people in order to exchange them for specific results (travel abroad, capture to avoid arrest for a crime committed, seizure by mentally ill people seeking to attract attention to themselves, the achievement of any political goals), then they are driven by instrumental motivation. It is in the case of such motivation that it makes sense to enter into negotiations, during which, through skillful psychological manipulations, it is possible to achieve success by lowering the level of readiness, alertness of terrorists, neutralizing it.
