San Francisco’s last gun shop, the High Bridge Arms, is scheduled to close later this month as a result of strict gun regulations in the city. According to The Guardian, gun dealers in San Francisco are required “to carry liability insurance, report inventory details and keep records of ammunition sales.” These regulations are in addition to the already strict state laws.

The Board of Supervisors passed a new city ordinance Tuesday, mandating the video recording of all gun and ammunition sales in San Francisco. It will also require gun dealers to keep specific records of ammunition sales and gun transfers, among other information, according to the ordinance’s text. Lastly, the recordings would be made available to law enforcement agencies.

San Francisco is taking the necessary preventative action by enforcing stricter gun control. These regulations are crucial barriers to ensure that San Francisco doesn’t succumb to the national threat of mass violence or become another pin in the latest map of our nation’s mass shootings.

A graph created by Slate clearly shows the emphatic correlation between gun control laws and lower rates of gun death. California’s laws were ranked the strongest in the U.S. Other states should take note.

For the small businesses and families that have lived in San Francisco, there is typically a real sense of loss in the community when a business goes under. The closing of San Francisco’s last gun shop is not one of those cases.

It’s hard to be opposed to the High Bridge Arms closure after the recent shooting at Umpqua Community College, where the shooter used firearms that he and members of his family legally purchased. It’s hard to be opposed to one less gun shop after a white supremacist killed nine people in a historically black church with a gun that he legally purchased because the examiner screwed up his background check. And it’s very, very hard to be sad about 1,000 fewer annual gun sales in San Francisco after the 2012 Sandy Hook shooting, when the shooter used guns his mother legally obtained to slaughter 26 people, mostly children.

It’s hard to say when the rest of America will have bled enough to wake up, or if we’ll just drift unconscious from the cumulative blood loss, but in the meantime, San Francisco needs to protect itself.
