Yet by your own admission poverty and inequality appear to account for the bulk of the effect.
Actually I think you'll find that plenty of Americans will acknowledge the link you point out. Just not in a politically charged exchange where the other party appears to have an ideological axe to grind. Where they'll likely disagree is the extent or significance of it. In many cases they will object that rights should never be curtailed for the purpose of lowering petty crime (I tend to agree).
I think it's also worth mentioning the statistic that legal gun owners (which is a wildly low bar in the US) have a lower rate of violent offense than the police.
That said, my point was that a place like Rio, where you feel alertness at a physiological level by the constant lack of security, still has a murder rate around Houston, a vastly richer and safer city.
And Brazil really is a good comparison in my opinion: the economic inequality is actually worse than in the USA, and they both have the slave holding history leading to concentrated poverty areas with high ethnic segregation
I don't personally think that the upsides of the US gun laws are worth anything near the downsides being paid.
Regarding the police, American police is notoriously prone to violence compared to other developed countries.
