The Addison Police Department has prepared an Annual Report for Calendar Year 2022. This report includes a statistical review of the year, notable events from the patrol and criminal investigation divisions, and goals and objectives for Fiscal Year 2023.
The Addison Police Department is also pleased to provide the results of an internal and external audit of its License Plate Recognition and Optical Camera system. This annual audit is assurance to the public, the department's License Plate Recognition and Optical Camera System has operated according to Council's policy direction, and that all internal activities surrounding its use were found to be in line with those adopted policies and procedures.
An important change in our reporting methodology took place in 2020. The Addison Police Department historically utilized the Uniform Crime Reporting (UCR) Program to track crime and clearance rates over time. Beginning in 2020, the Addison Police Department began using the National Incident Based Reporting System (NIBRS). Implemented to improve the overall quality of crime data collected by law enforcement, NIBRS captures details on each single crime incident as well as on separate offenses within the same incident. The additional data includes information on victims, known offenders, relationships between victims and offenders, arrestees, and property involved in crimes. NIBRS:
-
Provides greater specificity in reporting offenses. Not only does NIBRS look at all the offenses within an incident, but it also looks at many more offenses than UCR. NIBRS collects data for 52 offenses, plus 10 additional offenses for which only arrests are reported. UCR counts limited data for 10 offenses and 20 additional crimes for which only arrests are reported.
-
Collects more detailed information, including incident date and time, whether reported offenses were attempted or completed, expanded victim types, relationships of victims to offenders and offenses, demographic details, location data, property descriptions, drug types and quantities, the offender’s suspected use of drugs or alcohol, the involvement of gang activity, and whether a computer was used in the commission of the crime.
-
Helps give context to specific crime problems such as drug/narcotics and sex offenses, as well as issues like animal cruelty, identity theft, and computer hacking.
-
Provides greater analytic flexibility. Through NIBRS, data users can see many more facets of crime, as well as relationships and connections among these facets, than SRS provides.
When used to its full potential, NIBRS identifies, with precision, when and where crime takes place, what form it takes, and the characteristics of its victims and perpetrators. Armed with such information, law enforcement can better define the resources it needs to fight crime, as well as use those resources in the most efficient and effective manner.
Data collected prior to 2020 under UCR will show a much lower incidence of crime than the data collected under NIBRS because the UCR data only covers a narrow range of criminal activity compared to NIBRS. Comparisons between UCR and NIBRS data alone will not provide an accurate representation of the annual change in overall criminal activity. As we continue to collect our crime data using the NIBRS format, we will have a more accurate tool to see changes in activity should they occur.
