When a point is reached where the combination of threat-indicators meets a certain threshold, some consideration should also be given to the perception of the victim. In this analogy, a rush on the fence of a nation’s borders is no different to an attack on the members of a household. Using the power of disinformation, the public is manipulated into the perception that the victim is really the predator. The moral imperative is then placed on the individual under threat to justify any use of force to fend-off “the barbarians at the gate”.
