I refer the Minister to changes made by the police to the crime offence statistics since February 2001, and ask -
(1) Will the Minister provide a detailed explanation for all changes in definition of criminal offences?
(2) Will the Minister provide a detailed explanation for all changes in coding of criminal offences?
(3) Will the Minister provide a detailed explanation for all changes in reporting practices for criminal offences?
(4) Will the Minister provide a detailed explanation for all changes in recording of criminal offences?
(5) Will the Minister provide a detailed explanation for all processing changes in recording of criminal offences?
(6) Will the Minister provide a detailed analysis showing the impact from all those changes on the number of offences recorded for every offence category?
(7) If not, why not?
(8) Will the Minister table evidence to demonstrate that the decline in crime offences reported in the police reports since 2002 reflects real fall in crime as opposed to statistical changes?
(9) If not, why not?

From July 2001, the Police Service adopted the Australian Standard Offence Classification (ASOC). This is the standard classification of offences produced by the Australian Bureau of Statistics and replaced the previous ABS standard, the Australian National Classification of Offences. In addition to system changes, proactive policing strategies can encourage the reporting of certain offences, such as 'family and domestic violence' and 'sexual assault', for a particular period. Other initiatives that can increase the reporting of offences include the establishment of police facilities in new areas, such as remote communities, and partnerships with the building industry to facilitate the reporting of theft from building sites. By means of example, Homicide/Manslaughter/Driving Causing Death are offences for which changes have occurred. Being a statute-based system, the IMS does not differentiate between 'manslaughter' offences that involve the act of driving a vehicle and other 'manslaughter' offences. Consequently, the number of offences recorded under the offence category 'manslaughter', which is also a componenet of 'homicide', has been increased by the inclusion of some 'manslaughter' offences involving the act of driving a vehicle. In contrast, the number of offences recorded under the offence category 'driving causing death' is reduced by the exclusion of some 'manslaughter' offences involving the act of driving a vehicle and their inclusion under the more general category of 'manslaughter'. To overcome these recording issues, the offence 'driving causing death' has been removed and all 'driving causing death' offences have been incorporated within the offence category of 'manslaughter' with no loss in the total offence numbers. Policy changes in some sectors of the finance industry and recording issues associated with the initial roll out of IMS effected the number of fraud offences. The Police Service advise enhancements were made to the system to address this. Similarly, recording issues and reporting practices by agencies, local government authorities and private enterprises have impacted on the number of graffiti offences recorded. In terms of Sexual Assault, coding and recording issues associated with the offence categories of 'aggravated and non-aggravated sexual assault' have had an impact on the number of 'sexual assault' offences recorded. Under the OIS, 'indecent dealing' offences, which mainly comprise sexual offences against children, were categorised as 'non-aggravated sexual assault'. However, as the IMS is statute-based, 'indecent dealing' offences are not isolated from other sexual offences against children, most of which involve circumstances of aggravation. These offences have been re-coded as an 'aggravated sexual assault' and this has resulted in an increase in the number of recorded 'aggravated sexual assault' offences and a commensurate decrease in 'non aggravated sexual assault' offences. With regard to Aggravated Robbery, the introduction of the IMS has enabled improved recording of 'aggravated robbery' offences by allowing the inclusion of circumstances of aggravation not previously able to be recorded. These circumstances, which are reflected in statute, now include armed robbery, robbery in company and robbery committed against persons aged 60 and over. Police Service statistical officers expend considerable resources on quality assurance practices and procedures to ensure the statistical information published is of the highest quality. The auditing of the key performance indicators (KPIs) by the Office of the Auditor General (OAG) provides evidence of the quality of Police Service statistical data. The OAG opinion on audited KPIs is incorporated in the Western Australia Police Service Annual Report.
