Population differences. There is no correlation. Most gun owners are law abiding citizens so the number of guns is a non-issue. Areas with the highest concentration of gun owners and thus circulation of guns should have, according to you, a higher rate of gun violence. They do not.
lol ok i'll have one more go!
population differences= .... any explanation?
i agree most gun owners are likely to be law abiding citizens , as you said a "large portion" of gun crime(you think) is stolen guns being used, who are the criminals stealing the guns from....legal gun owners(?)
trafficking anything internally is pretty easy, could you honestly say that you think there is any city in your country ,high gun concentration(for the US) or not where a criminal would find difficulty getting their hands on a gun? it doesn't need to be a "high gun concentration area" per se, if wherever you are it's easy to get a firearm.
that is what i am saying is the difference ,it is not easy getting your hands on guns on the black market in the UK/europe due to there being a minute number of guns in circulation to start with.
