But if that sounded like a promising start to a conversation about the absurd profusion of guns in our society, including the military-style weapons used in both of this weekend’s massacres, think again. The moral of these two shootings, Mr. Ward said, is that we need more guns in more places. In El Paso, the shooting took place at a shopping center, a “gun-free zone," he said, and the assailant was able to kill 20. (That is, apparently, not actually true; the El Paso police chief says the suspect was well within his rights to walk into a Walmart with an assault rifle under Texas’ open carry laws.) The Dayton shooting, Mr. Ward noted, was stopped in under a minute by police who shot and killed the suspect. “The difference is ... there was a good guy with a gun in Dayton,” he said.
