Yes. In 2015, California Governor Jerry Brown signed Senate Bill 411 which clarified a person may lawfully record police officers in public or anywhere else the person has the right to be. This includes taking photographs, audio recordings, and video recordings. This Right to Record Act also decrees that recording a peace officer does not constitute reasonable suspicion for police to detain the person. Nor does it constitute probable cause for police to arrest the person. For example, simply recording a police officer does qualify as resisting arrest or obstructing an officer (PC 148).
