|All of those say what I said - US is much worse than any country of comparable wealth.|
The mistake you (and many people) are making is that the number of gun deaths is not necessarily tightly bound to the number of guns owned. Most people that own guns hardly ever use them. And very few have ever killed anyone with them.
Not counting accidental shootings (which I don't think we're talking about here), gun violence is a product (not a cause) of violent crime.
So the real question here is: Would limiting gun ownership reduce the amount of violent crime?
I don't see any evidence to suggest it would. People don't go out and commit crimes just because they have a gun. And keep in mind that you're talking about violent criminals here. If a violent criminal is willing to break the law and kill somebody... I doubt they'll have any reservations about obtaining a gun illegally.
Violent crime has far
more to do with social issues than gun issues. The US has high violent crime because:
1) Our education system sucks.
2) Our wealth distribution sucks
3) Our social programs suck.
These are the problems that cause the US to have higher death rates than other countries. If you compare education/wealth distribution/etc from the US to other countries, you will also see a pattern similar to that of gun ownership.
Gun control does not solve any of these issues. It's nothing more than a superficial knee-jerk reaction. It accomplishes very little, if anything.
