There's nothing wrong with guns themselves.
I come from a country where there's little regulation on guns. Hell, around here, you can go to a outdoorsy store and buy a shotgun hands down only requiring some documentation that proves you're +18 years old, yet we have 1/20 amount of gun-related deaths here compared to the U.S.
In the U.S. with all the gun toting, is due to its gun culture and whathaveyou which is the problem.
It was never a question of more or less guns, or even tighter gun control, it's the culture in which the guns exist that matters.
Sure, you might argue that gun themselves have an impact on how people react to guns, then why do other countries with little limit on gun control lesser gun related deaths than the U.S. per capita? Just look up the stats.
