That proves absolutly nothing. There are countries out there, with more Guns per capita then in the US, with some of the lowest crime rates in the world. And what charts are you looking at? Hopefully its not Wikipedia. If you go and get Interpol data, latest Interpol data shows that Croatia has a higher murder rate per capita then the US. Not to mention the murder rate in the US has been on a steady decrease for the past couple of decades.
Simply saying that banning guns reduces murder is absolutely ludicrous.
F*ck it, this topic is getting old, how about this, if you want to live in a place where guns are outlawed because you believe it increases the murder rate, then thats fine, get the fuck over that in the US we are allowed to own guns and stay the hell away from our country, simple as that. I dont see how in anyway it should effect you.
