I'm not actually that concerned with the police having any of that stuff as long as the population is armed (even with basic semi AR15's). Over and over we see the best equipped military struggle to control a population that has basic arms. When the populace is armed and threats can blend in with everyone else, you can only rule by consent of the people (or by killing everyone, but they don't have the stomach for that in mass).
That being said, read the ultimate intention here. Don't look a gift horse in the mouth. Weaken police. Get more of them shot. Use those shootings to build a case for more gun control.
