I think your missing the point more. Bad things can happen anywhere but less bad things happen when there are armed people around because now the bad guys are more likely to face even odds. Look at the statistics from cities like Washington DC or Chicago IL where you have very strict gun laws so there are high rate of crimes because there is less chance of being stopped. Criminals pick on the weak so when people are weakened by lawsthey make for easier targets. Looks at places where everyones grandma does tote an AK, crime is low there because criminals are going to be less likely to mug/rop/rape grandma.
The wild wild west didn't get its name because everyone was running around shooting everyone else, back then you typically carried a single shot or an early revolver and carried only a handful of bullets and those were more for getting your dinner rather than fighting bcause you couldn't drive down to the corner store to get more bullets you had to be very careful with how many you used.
