I have a relative whose wife told the elders he was physically abusing her. They wanted to meet with him. He wanted to prove his innocence and show that actually it was HER who was abusive so he videotaped several episodes of her fits of rage.
His elders (California) flatly refused to even look at the tapes. Legal must have told them that there must be consent to be taped and consent for said tape to be viewed by others.
