Fear If someone were to hold up a bank with a banana in his pocket, he would be charged with armed robbery. Clearly, no victim was in any danger of being shot, but it is the belief that the robber has a real gun that is considered by the law. And for good reason. Knowing full well that fear will motivate them to comply with his demands, the robber took steps to make his victims afraid. Fear, real or perceived, is arguably the most powerful manipulation of the lot.
