From the Guardian, of all places, and in the context of the Aurora shooting:

The key facts are:

• The US has the highest gun ownership rate in the world – an average of 88 per 100 people. That puts it first in the world for gun ownership – and even the number two country, Yemen, has significantly fewer – 54.8 per 100 people
• But the US does not have the worst firearm murder rate – that prize belongs to Honduras, El Salvador and Jamaica. In fact, the US is number 28, with a rate of 2.97 per 100,000 people

As the Guardian says, facts are sacred.
