Well, Zim doesn't have walk, but handgun sales are up again. And two states IL and (?) just passed relaxed CCW rules.
So, to me, it is either one or two things.
1 - no one has a weapon Impossible. And the more we try, the worse it gets. Blackmarket pressure trump un-popular laws.
2- everyone is armed, or at least knows how to conduct themselves. Every place we go, 50% of people are in open carry and possibly another 80% that are CCW. Pulling the weapon on someone will get you killed possibly by an armed bystander.
So, sadly, only 2 is possible, only 2 is the natural state of this world. And even in pastoral England, everyone was armed with something and could use the weapon they had.
