Are Americans more homicidal than everyone else?

“Compare the rate of murder by gun in the United States to the rate in any other advanced industrial nation, and you’re forced to draw one of two conclusions: Either there are far more homicidal people in this country than just about anyplace else on Earth, or far more guns,” columnist Harold Meyerson wrote. “We must either be home to more people who succumb to murderous rage or who kill out of the coldest of calculations, or it’s easier to pick up a gun and start shooting here than in any comparable country.” Meyerson noted that there are 3.2 gun homicides per 100,000 residents in the United States, while only 0.1 per 100,000 in France, Britain and Australia. “Want to argue that we have 32 times the rate of dangerous mental illness that they have in Australia?”
