With the rise of military policing, I've noticed something missing in the discussion, a comparison of law enforcement models. Nobody seems to be answering the question, for every particular jurisdiction, which of the three models available is best for fighting crime in that jurisdiction. The three models, in order of their invention, are hue and cry, peace officers, and military style policing. If you think the model list is too short, feel free to add to it in comments.
It's such a simple question, but nobody's asking it, nobody's answering it, and nobody's making adjustments to policing models in a systematic, scientific way. This is not rocket science. You don't need above average intelligence to do this task but people talk about the future where we'll have nothing to do and no way to earn our daily bread.
