Wouldn't it be a good idea to ask people who are already mandatory reporters how reporting works? Teachers, counselors, doctors, etc. are already mandatory reporters. There are laws protecting this confidential information from the public. So if a person is accused the only people who know are the investigators and the victim (the victim's family). Usually, at least in my little area of the world, there is an investigative team of law enforcement and mental health professionals who persons who have received years training..sometimes a guardian is appointed to advocate for the child victim. None of this becomes public unless there is sufficient evidence to bring the matter to court and charges are filed. These cases are very, very, very difficult to bring to trial. BTW, for mandatory reports working in mental health, the penalties for breaching confidentiality (releasing information to people not involved in the investigation) are in the thousands of dollars and possible jail time. And yes, I know that JW elders have trouble keeping things confidential.
