Coming back to the statistics,
In 2010, the rate of firearm homicide for blacks was 14.6
per 100,000, compared to 1.9 for whites, 2.7 for American
Indians and Alaska Natives, and 1.0 for Asians and Pacific
Islanders (figure 5).
UK had 33 firearms homicides in 2010 giving a rate of 0.04 per 100,000
Its definitely more dangerous (in terms of firearms deaths) to live in the USA instead of the UK but the risk is still low.
