Section 278: Suppression of riot by person acting under lawful orders

It is lawful for any person acting in good faith in obedience to orders, not manifestly
unlawful, given by a peace officer for the suppression of a riot, to use such force as he
believes, on reasonable grounds, to be necessary for carrying such orders into effect.
Whether any particular order so given is or is not manifestly lawful, is a question of
law.
