California police are refusing to release documents about the surveillance technology it uses, despite a new law that requires their release.

On January 1, SB 978 went into effect, which requires the Commission on Peace Officer Standards and Training (POST) to "conspicuously" publish all law enforcement agency training materials. The agency has said that it will not comply on copyright grounds.
