The problem is that it can take time before a determination is made as to who is the perpetrator and who is the victim. The leave will be pointless if it takes a year or two for the justice system to finally work out who the victim is and who the guilty party is. It takes way too long to identify who the victim in the situation is in order for real victims to access the leave.
