They didn't care, they did it anyway. Getting guns illegally isn't that hard. If two high school kids can do it, anyone can. Now lets look at examples of countries that allow their citizens to have guns. Take Switzerland for example.
Every household is required to have a fully automatic assault weapon and ammo.
This country boasts one of the lowest crime rates in the industrialized world. Well lets see. Well as you know they don't have an army. And after W.W.II they realized that being a neutral country with no army make them an easy target. I guarantee that the next time a Hitler wanna-be marches toward Switzerland every able man will grab their assault rifles and head to war.
