Perhaps it's because in the UK we have far more sense. Far more Americans are killed by fellow Americans with guns than by any foreigner or terrorist. In fact, far more Americans were killed by gun violence in 2013 alone (33,636) than all the Americans killed on U.S. soil by terrorists in the last 14 years, and that’s including 9/11. (2,977 Americans were killed on 9/11 and only 48 have been killed since by terrorism on U.S. soil.)
That's a bit of a non sequitur since no one mentioned terrorism in any posts since at least 2014. What's your point?
Anyhow, since you bring numbers up, about 30k die by the gun annually in the US. Of course, it isn't all cut and dry as that. About 20k Americans commit suicide using a gun. People have differing opinions on right to die, but it isn't legal most places here and people use what's most convenient and painless. Guns fit the bill.
Of the remaining 10k, about 500 are accidents. Stuff happens, and it's about the same as the number of recreational drownings not related to work or water transit. Go figure. Life is full of potential trouble and risk reward decisions. Stay away from guns and swimming pools if it helps.
Of the remaining 9500 deaths that aren't by choice or accident, they break down generally into incidental crimes, and crimes of passion. Nor argument there. They estimate 1400 people in Chicago along are responsible for about 80% of the murders. Personally, I'd say lock up the criminals if you want to decrease firearms murders, don't make me a criminal via some law.
Numbers are fun and all, but they don't mean much in apple to apple comparison when comparing nations due to differing accounting measures. UK and US are so different in this manner, it's really amazing to really dig into the FBI vs Home Office reporting and classification criteria. It's fun to compare and contrast differences, but when you have different basic definitions on what actually even gets reported as a murder, it makes it pretty tough to declare winning and losing policy.
Anyhow, I don't think you have far more sense in the UK. I think people are people wherever you go, and the US and UK are no exceptions. You may have a different perspective on some things, and that's fine by me. Allies don't have to be socially identical.
