I remember in the 90s, abused women waiting for their spouse to be bailed from court where I was on duty. She would know what to expect if she wasn't there, showing the world he was really a 'nice man.' The man would have in his hand a bail sheet bearing the condition 'not to appoach x directly or indirectly' and he would have broken bail before walking out of court. Police would be informed, no action woud be taken other than to police bail him and add breach of bail to his charges, and this would be addressed next time he appered at court, by which time she would have been assaulted again. Police were helpless to do anything other than follow the guidelines they had at the time.
It was only when the whole system was able to operate without the testimony of the victim, once her injuries had been photographed and she had made her initial complaint, if she was too frightened to continue, that prosecutions started to have some effect. The abuser would at last be seen as a high risk offender, victim protection was heavily resourced, and women started to have confidence in being able to free themselvesf from their abusers.
