If the mere prominence of firearms caused people to go around shooting other people willy-nilly, then the homicide rate here would look like that of a war zone. But it's a fraction of the big cities. Why is that? Because we're civilized, that's why.
Yes, Milwaukee has 10% of the population and 60% of the homicides. I believe the 1 CCW homicide was from Milwaukee, or at least the metroplex.
Take away the Milwaukee Homicides and Wisconsin’s homicide rate is about 1.24, a low rate for Europe.
