America is once again confronting shocking illustrations of the destruction of mass shootings, and advocates devoted to quitting weapons and a wave of angry people on social media are asking Walmart to do more.
The type of gun used in Saturday's attack has not been sold at Walmart in many years. But now that the firearm has hit Walmart's own stores when customers were at school with their children, many are wondering if the company will take further steps to limit firearms sales.
"As an employer and a place where a huge population of very diverse people act, it is in Walmart's interest to repeat what it will do to ensure that it is employers and its customers," said Kris Brown, president in the gun violence prevention advocacy group Brady.
Social media users ask Walmart to stop selling firearms
Venture capitalist and entrepreneur Chris Sacca had a similar response: "Hi @ Walmart, maybe you could, hmm, I don't know, stop selling guns?"
Others on Twitter asked the company to stop allowing open firearms in stores, something it says in states like Texas where open carry is legal.
However, Walmart already has what many gun violence advocates consider strong gun security policies that go beyond federal requirements: it does not sell assault weapons, it does not sell to people under 21, it requires background checks, and it no longer sells toys similar to assault rifles. .
While that doesn't change policy, many believe Walmart is positioned to push lawmakers to impose stricter gun restrictions.
"There is a role to play in leadership and advocacy here," Brown said. "Walmart has already implemented these policies on their own … They've done it because they're concerned about public safety if they don't. So why wouldn't they say from a national perspective if we want people to feel safe , should these steps be taken wider? "
And while Walmart is a big gun seller, there are many places where people can buy guns. Brown said the company should encourage other dealers to follow the lead in implementing safe firearm sales policies.
Walmart could also play a role in educating its customers about gun safety, said Texas Gun Sense president Ed Scruggs. Especially in rural communities, Walmart stores act as de-facto community houses that Scruggs said would make them sensible homes for educational programs.
"We have a problem in Texas with children and teens accessing firearms that are not properly stored," Scruggs said. "They may have free courses in the gun safety store or promote use or trigger locks or have big sales on gun drawers. Reaching out to the community may seem like a small thing, but they have an opportunity to reach many people."

"You know everyone talks about the thoughts and prayers that go out to them. It's great. It really doesn't do anything," Stack told CNN last year. "We felt we had to take a stand and do this."
Public statements like these make a difference, said Shannon Watts, founder of the firearms security group Moms Demand Action. And it may be faster and easier for large companies to introduce a new policy or public position than for legislators to draft and pass a new law.
"Getting Walmart to join the coalition of companies that are actively working on this issue, and making it a priority in their basic platform, would send a strong signal," Watts said. "Businesses have a role to play. When lawmakers don't protect their constituents, companies have a responsibility to protect their customers."
Walmart's immediate focus
Currently, about 36 hours after the attack, Walmart's policy remains the same, according to company spokeswoman Randy Hargrove. Hargrove also pointed out that the company has provided quarterly active shooting training for all employees since 2015, and that all the staff at the El Paso store that was targeted Saturday had been trained.
"We continue to be devastated by the loss of lives, and right now our focus is to support our colleagues, our customers and the El Paso community," Hargrove said.
