As used in Section 10.50.020 “public safety order” is an order issued by a peace officer designed and reasonably necessary to prevent or control a serious disorder and promote the safety of persons or property. No such order shall apply to a news reporter or other person observing or recording the events on behalf of the public press or other news media, unless he is physically obstructing lawful efforts by such officer to disperse the group. (Ord. 1145-85 § 62(1), 1985.)
