This is the first time that Her Majesty’s Inspectorate of Constabulary and Her Majesty’s Crown Prosecution Service Inspectorate have inspected and reported on the police service’s and Crown Prosecution Service’s approach to tackling crimes of harassment and stalking. Harassment and stalking crimes are damaging and pervade all sections of society. They can devastate lives and in some cases they end in death. In a digital world, they are crimes that can take place all too easily and frequently. They may be high-profile crimes and often gain the attention of the media when they affect public figures. However, the criminal justice system has a responsibility to all victims whatever the apparent level of seriousness of the actions complained about. This report must be a catalyst for change and improvement: in some cases victims’ lives will depend on it.
