Heather Mizeur wants to extend some of the restrictions on handguns to other guns as well.
Maryland gubernatorial candidate Heather Mizeur says she'll push for several new regulations on guns if she's elected.
Mizeur's proposals include universal background checks on all gun purchases — not just for handguns — as well as raising the minimum age to purchase any gun to 21.
Opponents of the expansive gun law that took effect in Maryland last year say the new restrictions still didn't prevent last month's fatal shooting at the mall in Columbia. Mizeur says while no law can prevent all incidences of gun violence, her proposals might have in the Columbia shooting.
"In this case, these proposals actually could have prevented that," Mizeur says. "Because the gentleman who purchased [the gun], while he passed a background check, he was under age 21. So he would not have had access to purchasing a gun."
The gunman in the Columbia shooting purchased the shotgun he used legally at a store in Montgomery County. Mizeur says her age requirement proposal is not a reaction to the shooting, as she and her campaign had been working on it in the weeks before the shooting.
