This is actually a really good example for why we don't want to ban weapons: Genocides are often perpetrated by the country the victims actually belong to.
Examples: Germany under Nazism, former Yugoslavia, Rwanda, -I'm fairly sure the list goes on.
I feel totally safe and I'm actually happy knowing that many of my neighbors have weapons. Especially here in Norway were I know there are strict background checks on who gets permits.
(For Americans: What I would do is start cooperating with NRA like Nordic countries has traditionally done with their local equivalents. Work not to prohibit guns but to promote safe storage and safe practices.)
