Vermont, Maine and New Hampshire have the most white populations, and their gun-related homicide rates are 0.3, 0.8 and 0.4 per 100,000 respectively. That's between 1.5 and 4 times the gun related homicide rate in the Netherlands. And that's the Netherlands as a whole, not a conveniently cherry picked stat that I've allowed for the US. I couldn't find a racial breakdown for Dutch murder rates either, not that it makes a difference.
I've had to use gun-related murder stats as I couldn't find comparable numbers for gun related violence.
