I was surprised to find that the UK death toll from guns so far in 2012 was 22. I couldn't find even vaguely current comparables for the US, but with a population 5 times ours they have more homicides per diem than we have per annum. Add the larger number of suicides, accidents etc and it's a humungous number. But they do on average own a gun each, that's 300m weapons.
They're never going to change. Its sort-of in the constitution if read with brain turned off. Mind you, their road death rate is over three times ours too.
Japan, which has tougher gun laws than us also has a lower death rate from them. Seems logical somewhow.
