The New York Times reports that Dick’s Sporting Goods, one of the U.S.’s largest sports retailers, will stop selling assault-style rifles and require gun buyers to be 21.

Edward Stack, the CEO, said the decision was a response to the Florida school massacre.

“When we saw what happened in Parkland, we were so disturbed and upset,” Mr. Stack said in an interview Tuesday evening. “We love these kids and their rallying cry, ‘enough is enough.’ It got to us.”

He added, “We’re going to take a stand and step up and tell people our view and, hopefully, bring people along into the conversation.”

Mr. Stack said he hoped that conversation would include politicians. As part of its stance, Dick’s is calling on elected officials to enact what it called “common sense gun reform’’ by passing laws to raise the minimum age to purchase guns to 21, to ban assault-type weapons and so-called bump stocks, and to conduct broader universal background checks that include mental-health information and previous interactions with law enforcement.

Mr. Stack said the retailer began scouring its purchase records shortly after the identity of the suspected Parkland shooter, Nikolas Cruz, became known. The company soon discovered it had legally sold a gun to Mr. Cruz in November, though it was not the gun or type of gun used in the school shooting.

“But it came to us that we could have been a part of this story,’’ he said. “We said, ‘We don’t want to be a part of this any longer,’” said Mr. Stack.

I guess Dick’s can forget about help from government in places like Georgia and, probably, Arkansas. Dick’s has stores in Conway, Hot Springs and Fort Smith. Go buy a gun from them (if you’re 21). They’ve earned consideration.
