Senate Bill 627, written by Sens. Scott Wiener, D-San Francisco, and Jesse Arreguín, D-Berkeley, includes exceptions for SWAT teams and others. The measure was introduced after the Trump administration ordered immigration raids throughout the Los Angeles area earlier this year.
Federal officers in army-green neck gaiters or other face coverings have jumped out of vans and cars to detain individuals across California this summer as part of President Donald Trump's mass deportation program, prompting a wave of criticism from Democratic leaders.
Representatives for the U.S. Department of Homeland Security defend the face coverings, arguing that identifying officers subjects to them to retaliation and violence.
If supported by Gov. Gavin Newsom, the law would apply to local and federal officers, but not state officers such as California Highway Patrol officers. Wiener, when asked about that exemption on the Senate floor, declined to elaborate.
Leaders in Los Angeles County are exploring a similar measure to ban masks despite some legal experts' view that the supremacy clause of the U.S. Constitution dictates that federal law takes precedence over state law.
The bill's backers argue that permitting officers to disguise themselves creates scenarios where impostors may stop and detain migrants, which undermines public trust and ultimately hinders legitimate law enforcement operations.
"The idea that in California we would have law enforcement officers running around with ski masks is terrifying," Wiener said in a brief interview. "It destroys confidence in law enforcement."
Wiener's bill allows exceptions for masks, including for undercover officers. Medical coverings are also allowed. .
Senate Bill 805, a measure by Sen. Sasha Renée Pérez, D-Alhambra, that targets immigration officers who are in plainclothes but don't identify themselves, also passed the state Legislature on Thursday.
Her bill requires law enforcement officers in plain clothes to display their agency, as well as either a badge number or name, with some exemptions.
