An odd-sounding statement, but accurate under Cal. Penal Code § 405a. From In re Anthony J. (Cal. App. 1999):
Under California law, “lynching” includes not only the notorious form of lynch mob behavior that aims to take vengeance on the victim, but also any participation in riotous conduct aimed at freeing a person from the custody of a peace officer. Accordingly, we conclude that a person who takes part in a riot leading to his escape from custody can be convicted of his own lynching.
