Via the SF Examiner:

San Francisco cracked down Tuesday on permitted concealed weapons by prohibiting them at public gatherings and events.

The Board of Supervisors unanimously approved legislation introduced by Supervisor Catherine Stefani that amends the police code to prohibit firearms at public gatherings like protests and parades in the public right of way and on parkland in the city. The legislation applies whenever there are 20 or more people participating in the event and within a 500-foot radius. Permits issued for the events will include the new firearm ban condition.

“Our first amendment rights, the freedom of speech and the right to peacefully assemble and protest, should not be infringed, chilled or suppressed by the presence of guns in our city,” Stefani said.
