“A shaila needs to first be asked whether the case reaches raglayim la’davar.”
R’Elyashiv z’tz’l may have been able to pasken that way in Israel. But if you are a mandated reporter in the US, you can’t ask a shilah and you must report. Furthermore, some states — New Jersey is one of them — make EVERYONE a mandated reporter. If you or your rabbi has trouble with that, you need to live somewhere other than New Jersey and you need not to be a mandated reporter in the state in which you live.
