>Per-capita firearm-related deaths in Switzerland are 7 times lower than in the US

If you break gun violence down in the US by race, you get results that are much closer to Europe.

>Nationally, the U.S. gun homicide rate (per 100,000 people) in 2020 was 26.6 for people identified as Non-Hispanic Black, compared to 2.2 for those identified as Non-Hispanic white and 4.5 for Hispanic individuals of any race.
