This circles back to my comment about nonchalance. It appears too many Americans are too comfortable around guns, and that’s not always (or maybe not even mostly) because they’re expertly-trained to handle them. I believe much of it has to do with their ubiquity, both physical (they’re all around us) and cultural (they’re everywhere in TV, movies, news stories, social media, etc.). I can envision where such comfort around something so dangerous can extend to even situations that are supposed to be airtight with their caution.
