Why would they (the abusing men) stop if they can get away with it when no authority is brought into play? Sometimes the offender is the big brother. Or the brother in law, or the next door neighbor. Or your sister's boyfriend. Sometimes it is a total stranger, and sometimes it is most or all of the above. When the innocent have no authority and feel there is nobody they can turn to, it is a burden carried for many years that shapes their beliefs and who they become in life.No need to use authority. There's other ways to make them stop or let your big brother handle it.
