In sifting through the facts about the gun debate, beware of the misleading use of statistics.

Take for example, “fact” number five on the main Vox card on this issue. It contains a chart from Mother Jones, which is presented to make the case — as Mother Jones puts it — that “People with more guns tend to kill more people — with guns.” Or as Vox puts it, “More guns, more violence.” Both statements are false, but this chart at least seems convincing.
