San Francisco police chief bans 'thin blue line' face masks

SAN FRANCISCO — San Francisco’s police chief said the city’s rank and file will wear neutral face coverings to defuse a controversy after officers sent to patrol a May Day protest wore masks adorned with the “thin blue line” flag.

The police union ordered and distributed the masks emblazoned with black-and-white American flag with a blue stripe across the middle. The symbol is associated with the Blue Lives Matter movement, a display of unity among police officers in response to the national Black Lives Matter movement.

In an email obtained by KTVU-TV, Chief Bill Scott told his officers Friday he considered the blue flag and stripe “a meaningful expression to honor fallen officers.” However, he worried some may perceive the symbol as “divisive and disrespectful.”

A retired civil rights lawyer told the San Francisco Examiner the masks, which include the logo for the San Francisco Police Officers Association, violate a longstanding policy that bars police from expressing political opinions while wearing their uniforms.

“The definition of a uniform is that it’s uniform,” Crew said. “There is no option to add your own statements, affiliations, whatever.”

The police union president, Tony Montoya, said the union showed the masks to Scott’s command staff and several of them had asked for more. The blue line “represents law enforcement’s separation of order and chaos,” he said.
