Studies have shown that issuing a protective order or arresting a person who commits an act of domestic violence does reduce future incidents of domestic violence. When perpetrators of domestic violence see that the police and court system will treat domestic violence seriously, many persons who commit domestic violence may be deterred from future violence.
But orders of protection are not guarantees of protection or safety. For some individuals with intense anger or rage, no court order will stop their violence, and a court order might even add to the rage. Newspapers periodically carry stories of women murdered by their husband or boyfriend despite numerous arrests and orders of protection. The legal system cannot offer perfect protection, although it can reduce violence.
