Not many guns nor much ammunition is sold in San Francisco, but Supervisor Mark Farrell wants to record those transactions.

He’s asking the city attorney to draft legislation to require the video recording of all such commercial sales in the city, as well as require businesses to give the Police Department weekly updates on their ammunition sales.

The legislation would affect the only store in San Francisco that sells guns: High Bridge Arms, which is near the intersection of Mission and Valenica streets. Several calls to High Bridge Arms went unanswered.

Farrell said the fact that legislation affects just one store misses the point.

“This is about putting a framework in place for any store that exists today and any stores that are thinking about coming to San Francisco in the future,” he said. “Anything we can do to promote gun control in San Francisco while also aiding our Police Department in their investigations is something we can actively support and do at the Board of Supervisors.”

San Francisco already has some of the strictest gun laws in the country. Handgun owners are required to keep their weapons locked when stored at home, and the city bans bullets that expand or splinter on contact. But to date, it does not require the video recording of sales or require sellers to give weekly updates about ammunition sales, Farrell said.

Watch those words: A campaign urging people to conserve water has gotten flak for its tone-deaf slogan: “Beating the Drought is Quick & Easy.”

Though well intentioned, the San Francisco Public Utilities Commission campaign oversimplifies the solution for a drought that is anything but quick and easy.

“As we were developing the campaign, we thought about the typical doom-and-gloom scenario,” SFPUC spokesman Tyrone Jue said. “This is about saying conservation can be fun. It can be something that is exciting and easy to do and something everyone needs to do. The message is clear that here is an easy and simple way for you to save water today.”

Tips include taking shorter showers and upgrading to a more efficient washing machine. They’re important, but they won’t alone alleviate the drought. Still, Jue said, the city has conserved 11.6 percent more water this year compared with last.

“All we wanted to do was make people realize it doesn’t take a lot to start conserving,” Jue said. “The ultimate message is getting everyone to do his or her part.”

Results are being seen, but they still might want to rethink that slogan.
