Although it's worth pointing out that some of the worst US mass murders were arsons, such as https://en.wikipedia.org/wiki/Dupont_Plaza_Hotel_arson https://en.wikipedia.org/wiki/Dupont_Plaza_Hotel_arson and there's one I'm having difficultly finding that was almost as bad set in the entrance of a NYC nightclub. That people in the US choose guns vs. fire is I'm sure cultural, including fire safety being part of our culture, i.e. the "payoff" will seldom be great.
