Ira Williams, 42, went to the Woodforest Bank inside the Walmart conceal-carrying his handgun. The Houston father of three said he didn’t want to go to the bank, but needed some cash to pay some bills. Williams, who worked as a Target security guard for two years while he was in college, called on Walmart to hire local police officers to patrol store aisles.

“I would feel more protected if they had three or four police officers patrolling the store,” Williams said.

Shoppers also debated various gun legislation, such as background checks, and what retailers could do to curb gun violence across the country. Walmart in 2015 stopped selling assault-style rifles, and last year raised the minimum age for gun sales to 21 in the wake of the Parkland, Fla., school shooting.

Reyes, the Houston mother, said Walmart shouldn’t be in the business of selling rifles, and called for stricter background checks.

“AR-15s aren’t for any normal people,” Reyes said. “Living in the city, we don’t need guns like that.”

Williams, the Houston father with a concealed-carry permit, agreed, saying assault rifles should only be for police officers and the military. However, he said bans on firearm sales is not the answer to solving American’s gun violence.

“I don’t want to take people’s guns away, but AR-15s and Ak-47s are not for normal citizens,” Williams said. “I’m for background checks. Congress needed to pass that like yesterday.”

Yazmin Villarreal, 26, made her twice-weekly trip to that Walmart to grab some diapers for her sister’s baby and to pick-up her prescription medication. Her husband, worried about mass shootings, had given her an electric stun gun, and is now teaching her how to use a handgun, she said.

“Shootings are an everyday thing now,” Villarreal said. “You never know when it might happen.”
