Like these jackasses[0]. You want to give these people the right to arbitrarily arrest, detain and kill because two centuries ago Thomas Jefferson saw the horrors of the French Revolution, got the biggest boner of his life and thought "how about that, but a whole country, all the time?"
No thank you. I don't trust the cops but I trust my fellow armed Americans even less. At least the police, ostensibly, have a system they have to abide by other than a piece of parchment saying "everyone gets as many guns as they want, no questions asked." What you're advocating is essentially gang warfare.
Also, "freedom isn't free" became popular as a meme from South Park making fun of the wave of jingoistic, patriotic BS songs after 9/11.
It costs a buck o'five, by the way.
