"There are more than twice as many gun stores in America as McDonalds restaurants. There are only 14,098 McDonalds. American gun companies made 5.5 million new guns in 2010 and 95% of them were sold to Americans. These ~5 million guns weren't nearly enough to satisfy American demand for guns in 2010, so an additional 3.3 million guns were imported. There were 16.5 million background checks for gun purchases in 2010. You can get a gun unless you have a criminal record or are evidently insane. 47,856 people were murdered in the U.S. with guns from 2006-2010. This was more than twice as many people as those killed by all other methods combined."
