having dealt with a real life high-level sociopath (my father sadly), I can tell you as a matter of fact that the police, the legal system, the medical system, the psychiatric system... all the systems in place are not equipped to deal with these extreme types on the fringe. In the end, they are people in these positions of responsibility, and are either scared or unwilling to deal with "possibilities" of violence. Their job is to react to evidence, and their job is on the line if they preemptively deal with these people. My point is, human beings are mostly cowards that cannot deal with this stuff.
