The United Kingdom has one of the lowest rates of gun homicides in the world with 0.07 recorded intentional homicides committed with a firearm per 100,000 inhabitants in 2009 compared to the United States' 3.0 (over 40 times higher) and to Germany's 0.21 (3 times higher).
OK, but what is the MURDER
I guess it's now considered a worse thing, in some places, to kill your attacker with a gun (that would be recorded as an "intentional homicide committed with a firearm", would it not?) than to be beaten to death by that attacker (that would be a "murder").
I'll keep my gun, thankee. You keep your moral superiority, such as it is.....
