America’s assault-weapons laws seem a failure. The federal ban, enacted in 1994, did not demonstrably reduce violence and was allowed to expire 10 years later. State-level equivalents seem equally ineffective. In California, whose 1989 assault-weapons act was first in the nation, gunmen armed with .223- and 7.62 mm-caliber rifles, respectively, took the lives of Sacramento police officer Tara O’Sullivan in June and California Highway Patrol officer Andre Moye just last month. Another gunman killed three people and wounded a dozen more at an outdoor festival in July.
So should we give up on banning dangerous firearms? Absolutely not. The reason these laws have proved ineffective isn’t because a ban can’t work; it’s because none have addressed the underlying characteristic that makes some firearms so lethal in the first place: their ballistics.
After O’Sullivan’s death, Sacramento’s grieving police chief pointed out that “bulletproof” vests are no match for high-powered rifles. He’s correct. According to FBI data, 471 police officers were feloniously shot and killed in the United States during the past decade. More than 100 were killed by rifles, 65 in the powerful .223, 5.56 mm and 7.62 mm calibers common to assault-style weapons. Rifles also figured in 20 of the 21 fatalities caused by rounds that penetrated body armor.
California, six other states and the District of Columbia “ban” assault-style weapons. But these laws skirt around caliber. Instead, they focus on a weapon’s physical attributes. For example, California requires that semiautomatic firearms with external baubles such as handgrips have non-detachable magazines. It limits ammunition capacity to 10 rounds.
Those characteristics, though, aren’t the main reason assault-style weapons are so dangerous. It’s fundamentally a matter of ballistics. High-energy, high-velocity .223-, 5.56- and 7.62-caliber projectiles have unbelievable penetration power. When these bullets pierce flesh, they produce massive wound cavities, pulverizing blood vessels and destroying nearby organs. Rifles can deliver this mayhem from a distance. That’s what happened in 2017 when an ostensibly law-abiding gambler opened fire with AR-15-type rifles from his Las Vegas hotel room, killing 58 and wounding more than 400 others.
Such shooting massacres have become commonplace. On Aug. 3, a 21-year-old man allegedly used an AK-47-style rifle to kill 22 and wound more than two dozen at an El Paso shopping center. One day later, a 24-year-old man donned body armor, grabbed an AR-15-type rifle and burst into a Dayton, Ohio, nightclub, killing nine and wounding more than two dozen. Then came the carnage in West Texas where another AR-15-style rifle was used to kill seven and wound 22, including three police officers.
Despite the deplorable toll, not one state has dared address ballistics. Why? Because it might offend hobbyists who get a thrill from tinkering with powerful guns, as well as citizens who want such weapons for self-defense. It would also threaten the interests of a powerful gun industry whose economic viability depends on producing and importing ever-more-formidable hardware.
So lawmakers have chipped away at the margins — say, by limiting ammunition capacity. But even 10 highly lethal rounds are an awful lot. With guns and gun parts readily available from private parties and through the Internet, restrictions on how weapons are configured are also easy to circumvent.
Bottom line: Many semiautomatic firearms are exceptionally lethal whether they’re short- or long-barreled, have handgrips or extended magazines. What to do? Following the examples set by Britain and New Zealand, we could ban them outright. Or we could create a scale of lethality, assigning scores for penetration ability and wounding effect along with ammunition capacity, rate of fire and accuracy at range. Guns that wind up at the dangerous extreme could be prohibited; others would be subject to a range of controls.
Of course, even the best-crafted scale won’t solve our epidemic of gun violence. By all means, expand background checks and implement “red flag” laws. But don’t use that as an excuse to keep ignoring what lies at the root of the mayhem: fearsome ballistics.
