"Warns that serious offences such as domestic violence, sexual assaults, offences against children and white collar crime are not adequately measured by official statistics. As a result the government's strategy to focus on known offenders is likely to see their crimes being ignored.
The paper argues that claims suggesting 5,000 prolific offenders commit nearly 10 per cent of all crime is "manifestly incorrect" and based on information about those convicted of crime, not those who commit it. Less than three per cent of known crime results in an offender being successfully prosecuted.
The paper goes on to criticise the government's use of the authoritative British Crime Survey (BCS). Though a more accurate measure of some crime than statistics recorded by the police, the BCS tells us little or nothing about a range of crimes, including sexual assaults, crimes against children, and white collar crime."
