Long-term implications of early experiences with policing
University of Manchester
This presentation is loosely based on two related but separate working papers
Funded by two small research grants

Most criminological research on procedural justice
“Each of these police-citizen contacts is potentially a ‘teachable moment’ about policing for both citizens and police” (Tyler, Fagan, and Geller 2014, 752)
Encounters are not evaluated on a blank slate
\(\leadsto\) Experiences with law enforcement accumulate over time
\(\leadsto\) Encounters are embedded within broader trajectories of repeated experiences and neighbourhood socialisation
“The idea of cumulative disadvantage draws on a dynamic conceptualization of social control over the life course, integrated with the one theoretical perspective in criminology that is inherently developmental in nature—labeling theory” (Sampson and Laub 1997, 1–3)
A developmental theory focused on dynamic processes
Cumulative disadvantage mechanism
Turning points and redirected trajectories
Labelling mechanism: individuals labelled as others and excluded from the body politic
Reframe experiences with unjust policing as cumulative, developmental, and contextual
Each individual event remains a teachable moment, but they are embedded within trajectories of exposure across the life course
Encounters communicate inclusion or exclusion — but we need to situate those signals within the temporal, cultural, and structural contexts in which they are lived
“I was eight when I first got stopped. (…) Thirteen, fourteen, that’s when I get stopped at least three times a week” (Haldipur 2018, 43)
Accumulated experiences of unjust policing across the life course
\(\Rightarrow\) socialization context of cumulative injustice
British Cohort Study
Measures
Growth curve model
\(\leadsto\) Multilevel growth curve model specified with a logistic function link and interaction terms
Average developmental trajectory of legal cynicism in the UK1
Effects of the number of police stops in adolescence on developmental trajectories of legal cynicism
Group-based trajectory modelling
Group-based trajectory modelling
From isolated encounters to cumulative trajectories
Cumulative injustice: A research agenda focused on cumulative exposures to unjust policing across the life course
\(\leadsto\) A life-course approach to procedural justice theory
