Statutory mandatory reporting yes however whilst there are arguments against mandatory reporting, many organisations have implemented a mandatory reporting policy regardless of what the local laws are.
Even if the WTS held back from implementing this themselves they also fall short from any form of pro-active support of the victim. They are simply told to make sure the victim and family are informed they can go to the authorities but given no support to do this. They should be doing everything possible to support the victim and help them get the right help as well as ensure the authorities are able to investigate an allegation so that the risk of leaving a predatory sexual abuser free to do whatever they want is minimised as far as humanly possible.
