Haven't verified numbers, but would guess that smaller % of black Americans own guns due to social criminalization of it. So only bad guys own for the most part, thus the murder rate.
certainly a possibility. there is definitely a culture surrounding guns that, while welcoming, takes some effort to get in to.
You're not lying. It warms the cockles of my heart every time I visit my range in the Deep South. There're always blacks & whites exercising our rights together & there's camaraderie.
