See people here think that a person can be held liable for not protecting or reporting a crime committed against a third party. If I am walking down the street and see someone being rapped and in fact have the ability to stop it but I dont guess what, I have not committed a crime and cannot be held liable to that victim. The only time I would be is if I was legally required too.
There is no where in Montana law that says a normal person must report child abuse.
Look at this montana case. Why didnt alexis sue her mother who knew her stepfather abused her sister and still delivered her to him repeatedly. Or even in the supreme court case it was brought up that the sherrieffs department didnt investigate because under montana law they weren't required to nor required to report to child services at the state level.
