Project Main Description: 

This study will shed light on how policy gets formed by police, and what influences the policy formulation process. Two policy case studies: drug detection dogs and police attendance at drug overdose, will be used to test two very prominent policy process theories: Kingdon’s Multiple Streams and Sabatier’s Advocacy Coalition Framework. Examination of these policy process theories in the context of policing of illicit drugs has the potential to provide significant new insights about the interface of science and policy, such that more effective drug policies become possible.

Through a comparative case study approach, this project will:
  1. assess the scientific merit of the two competing policy process theories (across the two case studies); 
  2. examine their applicability to the unique policing context; and 
  3. study the ways in which each theory can account for the interface between science and policy. 
Design and Method: 
Documents describing the events and activities around the policy developments for the two case studies will be reviewed. Interviews will be conducted with experts who were involved in the two case studies. From the documentary review and expert interviews, we will develop a narrative that conforms to each of the two policy theories. These narratives (one for Kingdon’s Multiple Streams and one for Sabatier’s Advocacy Coalition framework) will then be analysed for congruence, explanatory power, and face validity with police, and the relationship between science and policy teased out.

This project is nearing completion, pending final publications to arise.

This project will create new knowledge in relation to:
  • The scientific merit of two competing policy theoretical frameworks, and contribute amendments and improvements to the theories;
  • New insights into how well such theories apply to street-level policing
  • Comprehensive timelines and a narrative description of two case studies – of use to police and policy researchers 
  • Better understanding of the dynamic relationship between science and policy
