Accidents are not the same as intentional homicides, and should not be treated as such.<p>You do have a point re: arms races between the police and the rest of the country, but I&#x27;d argue that letting the police up the ante is a mistake. It&#x27;s better for both sides to be armed equally, as this discourages officers from abusing their power (and vice versa).<p>As for lumping states together, there&#x27;s a reason you don&#x27;t do that, and it&#x27;s codified in something called the Scientific Method. If you want to measure the effects of a certain well on iklness, you must count the users of that well separately from users of other wells, even if the wells are right next to each other. If you lump two wells together, then you don&#x27;t know which well actually caused the illness.
