“(1) There is a general presumption that information should not be disclosed, such a presumption being based on a recognition of (a) the potentially serious effect on the ability of the convicted people to lead a normal life; (b) the risk of violence to such people; and (c) the risk that disclosure might drive them underground. (2) There is a strong public interest in ensuring that police are able to disclose information about offenders where that is necessary for the prevention or detection of crime, or for the protection of young or other vulnerable people. (3) Each case should be considered carefully on its particular facts, assessing the risk posed by the individual offender; the vulnerability of those who may be at risk; and the impact of disclosure on the offender.”
