The other thing is that holding up Switzerland as an example only opens the door for the gun grabbers to talk about Japan, where the Olympic shooting team has to go to South Korea to train, and crime is very low. It's kind of an apples to oranges comparison, and the grabbers have been doing it for years. For example, the UK has a lower crime rate than we do, in fact, most countries do. But that doesn't really mean anything, and we can go back and forth comparing violent crime rates in the US, Switzerland, Japan, New York, Texas, Hawaii, Montana, on and on. Hawaii will have a low crime rate regardless of gun laws, mostly due to the culture here. My home state of Montana is quite safe, as well, despite boasting one of the highest rates of firearms saturation in the country. People here and in Montana have a long tradition of strong family ties and a sense of community.
Crime rates in different areas with different cultures are totally inconsistent, and leads to circular arguments. However, the rate of crime in the same places over time, and as gun laws change, is completely consistent, no matter where in the world you look. The crime rate in US states that loosened their CCW restrictions went down. The crime rate in the UK, Australia, and Canada shot up after they banned firearms. Don't be fooled by the Brady Bunch's bullshit when they start running off at the mouth about how much lower the crime rate is in the UK--those people are constantly writing editorials in their news outlets to decry the fact that, by their standards, they're awash in violence. Same goes for Canada and Australia. Different cultures have different crime rates, but freely acquired and carried firearms keep the crime rate low.
