(2) A person duly authorised by warrant or other legal process to arrest or detain a person for committing an indictable offence may, if that other person has notice or believes that such warrant or other legal process is in force against him or her, may use such force as is reasonable for his or her arrest, detention, or recapture, and may kill that other person if that other person cannot otherwise be arrested, detained, or retaken by any other means even though the offence was not committed by the other person, or no such offence has in fact been committed.
