(b) The official report of the law enforcement agency shall create a rebuttable presumption of good faith and reasonableness on the part of the person who assists the law enforcement officer.

(c) The purpose of this Code section is to provide for those persons who act in good faith to assist law enforcement officers whose health and safety is being adversely affected and threatened by the conduct of any other person or persons.
