"Most crimes are adaptive, normal, and easy to understand, and (in legalistic terms) all crime can be explained by the existence of a criminal law prohibiting such behavior (Robinson, 2004). Some crimes are much more difficult to understand and explain. It is not hard to comprehend why someone would steal because they’re hungry or to support a drug addiction. But understanding an explaining why a woman would shoot a pregnant acquaintance in the head and then cut out her fetus or why a young man would abduct, rape, torture, and murder a child is much more difficult and requires attention to research and theory from multiple disciplines."
