Media stories in the wake of mass shootings typically feature a laundry list of mistakes that reflect their writers’ inexperience with guns and gun culture. Some of them are small but telling: conflating automatic and semi-automatic weapons, assault rifle and assault weapon, caliber and gauge—all demonstrating a general lack of familiarity with firearms. Some of them are bigger. Like calling for “common-sense gun control” and “universal background checks” after instances in which a shooter purchased a gun legally and passed background checks. Or focusing on mass shootings involving assault weapons—and thereby ignoring statistics that show that far more people die from handguns.

Considering that a quick online search should provide all the information journalists need to get this right, it’s amazing that journalists don’t know the difference between an assault rifle and an assault weapon. An assault rifle is a fully automatic weapon that can fire multiple rounds with a single pull of the trigger, up to 950 rounds per minute. An assault weapon is a semi-automatic gun that can accept detachable magazines and has a pistol grip and foldable stock (to increase the gun’s length). The term assault weapon itself, of disputed origin, is a thorn in the side of gun enthusiasts, who point out that the differences between “assault weapons” and other semi-automatics are largely cosmetic and don’t increase the gun’s lethality…

That gun writers crow when the media makes mistakes like this indicates how little regard there is for the media from the pro-gun community. There are several ways the media can remedy this situation. For starters, treat guns like any other beat (as the Guardian has done with Lois Beckett). Media outlets tend not to send sports writers to cover the Supreme Court or style writers to cover a murder. Ignorance undermines authority. If you want to report on guns, you need to understand the differences between various weapons and how they are used. Spend time at a shooting range and learn how to fire a gun. Be able to interview an NRA member without scorn or derision.
