Gun control groups in the Chicago area are pressuring retailers to prohibit concealed carry permit holders from carrying guns on their premises.

The groups want retailers to put signs on their doors announcing that the business is a gun-free zone.

According to the Chicago Tribune, small groups of gun controllers are carrying out this effort, picketing outside a given retailer in hopes of pressuring the owner into cooperating. Two of the groups, “the Northbrook-based Peaceful Communities and Highland Park-based Joint Action Committee for Political Affairs,” are among those “urging [businesses] … to display no-gun signs–featuring the black silhouette of a handgun inside a red circle-backslash symbol–on doors and storefront windows.”

The Tribune reports the anti-concealed carry campaign has found “some successes,” but “many stores have resisted the campaign.”

Lee Goodman is one of the protesters calling for businesses to prohibit concealed carry. Goodman said, “For two years, we’ve waited and hoped stores would act responsibly, and very, very few of them have on their own, and it seems to be that many stores think of it as a way of not taking a stand they see as political, which might alienate some of their customers.”

Goodman participated in “a protest outside a newly opened Mariano’s in Northbrook [in August 2015], asserting the store was unsafe without the ban.” Goodman did not explain how disarming law-abiding citizens makes a store safer.
