Crime Linkage Practice in New Zealand
Purpose: To understand: (i)how crime linkage is currently performed with residential burglaries in New Zealand; (ii)the factors that promote/hinder accurate crime linkage ; (iii)whether computerised decision-support tools might assist crime linkage practice.
Methodology: Thirty-nine New Zealand Police staff completed a questionnaire/interview/focus group relating to the process, challenges, products and uses of crime linkage with residential burglary in New Zealand. These data (alongside four redacted crime linkage reports) were subjected to thematic analysis.
Findings: The data clearly indicated wide variation in crime linkage process, methods and products (Theme One). Furthermore, a number of factors were identified that impacted on crime linkage practice (Theme Two).
Research Implications: Future research should develop computerised crime linkage decision-support tools and evaluate their ability to enhance crime linkage practice. Also, researchers should explore the use of crime linkage in court proceedings.
Practical Implications: To overcome the barriers identified in the current study, greater training in and understanding of crime linkage is needed. Moreover, efforts to enhance the quality of crime data recorded by the police will only serve to enhance crime linkage practice.
Social Implications: By enhancing crime linkage practice, opportunities to reduce crime, protect the public and deliver justice for victims will be maximised.
Originality/Value: The practice of crime linkage is under-researched, which makes it difficult to determine if/how existing empirical research can be used to support ongoing police investigations. The current project fills that gap by providing a national overview of crime linkage practice in New Zealand; a country where crime linkage is regularly conducted by the Police but no published linkage research exists.
