Illustrations (a) The sections, in this Code, which contain definitions ofoffences, do not express that a child under seven years of age cannotcommit such offences; but the definitions are to be understood subjectto the general exception which provides that nothing shall be anoffence which done by child under seven years of age. (b) A, a police-officer, without warrant, apprehends Z who hascommitted murder.
