I don't have a civil right to break the law and victimize you. And if in so doing my activity poses a serious threat to an innocent victim or to a cop (running away usually doesn't do that) who is trying to arrest me, then of course the cop can escalate and escalate and escalate until there is nothing left to do but end my life.
I don't know where people get the harebrained idea that because we have inviolable constitutional freedoms in this country that we can go around freely victimizing the rest of society our entire lives without consequence or interference from the police. The cops ARE going to interfere. That's their job. They are going to stop you, or try to. And if you don't get that, you are going to die and the rest of us won't be shedding any tears for you. The law-abiding citizen has rights, too, and the cops are there to enforce them.
Oh, goody. Summary executions. I see.
