The elites know, or should know, for example, that the gun ownership rate in Switzerland is almost 50 per hundred people (easily enough for one gun per household, on average), yet the murder rate is something like the 10th lowest in the world. Maybe Marianne, who lives in Switzerland, can tell us more about this.
