Indeed. But it's not that other countries never had arms, they just gave them up. Notably, and relatively recently (historically speaking) Australia and Great Britain. That's the insidious thing that some governments do. If they don't take them away by force, they convince the citizens to give them up peacefully, for the 'good of society.' They emphasize the rare crazy person on a shooting spree and cleverly never, ever, ever mention that (at least in the case of the USA) we have them to keep our government in check. To protect ourselves from the tyrants that inevitably come to control. So many brain dead people never think about this. When governments disarm the people, the people are no longer free.
