Switzerland is a free and prosperous nation. They have a high standard of living. They have a very low crime rate. They also have compulsory military service for every man and woman, and they KEEP their service weapons when they go back to civilian life. They are expected to maintain readiness to defend their homes and their country, much like the Minutemen of our own Revolutionary War. Logic would suggest that the reason why they've managed to keep their freedom, their soveriegnty and their improbably low crime rate is because any potential burglar or invader KNOWS that there is someone in every single house with a military-grade weapon and the knowledge of how to use it.
