"If we really think these things should be off the street, we need to destroy them, '" he added.
"We found out that we sold this kid a shotgun", Stack continued.
"Ed's toughest business decision came in the wake of yet another school shooting; this one at Marjory Stoneman Douglas High School in Parkland, Florida, in 2018".
He then revealed that on top of the financial losses, Dick's destroyed all of the assault rifles the company had in stock, about $5 million worth.
Stack says the company, which has 720 stores in 47 states, destroyed over $5 million worth of the weapons formerly sold by the outdoor sporting goods company. "We just didn't want to sell the assault-style weapons that could inflict that kind of damage".
Stack also said that many stores have stopped selling firearms all together.More news: Christian Pulisic's Chelsea troubles: Frank Lampard admits to 'harsh' decisions

'All we were going to do was just take it off the shelf and not say anything, ' Stack said. He thought he would receive some flak but he didn't expect the feedback he did.
That shooting was close to home for Stack because Dick's sold a gun to the former student suspected the shooting, he told Cowan.
Even though it wasn't the weapon used in the shooting, that largely impacted the company's actions.
After the 2012 Sandy Hook Elementary school shooting in Newton, Conn., he said he ordered all the AR-15 semi-automatic rifles to be removed from all the stores across the country.
Walmart also asked their customers to no longer openly carry guns into their stores, even if it's legally permissable to do so in their state.
Stack said he's faced similar backlash for decisions he's made at Dick's.
Stack's new policy decisions received praise from Democratic presidential candidate Beto O'Rourke on Monday, who tweeted that the company is doing more to keep America safe from gun violence than Congress. Walmart stopped selling AR-15s in 2015 and in August they chose to stop selling some types of ammunition.
