Seattle Mayor Mike McGinn, a Democrat, is inviting local merchants to voluntarily post “Gun Free Zone” signs in their businesses, letting customers who have guns know they should shop elsewhere.
“We are here to support businesses that do not wish to have guns on their premises” McGinn said in a press release issued by Washington CeaseFire, which is partnering with the mayor for the campaign. “The police department regularly enforces trespass laws when a visitor to a business violates that business’s rules.”
“We will continue to do so, and I thank these businesses for standing up for the safety of their customers,” McGinn said.
