It's not like that in all countries, though. If the technology was inevitably reaching everybody, then guns would be readily available independently of cultural and political frame.
I'll also note that a high number of guns per inhabitants is not always correlated with a large number of firearms crimes (see Finland or Switzerland). On the other hand, you have enough examples of lunatics killing a large number of people with modern firearms that I feel a lot safer in a place with tight gun laws than I would feel elsewhere.
