Fulbright Scholarship Fellow Associate Professor Christopher M. Campbell will deliver a seminar on their research, fully titled 'Time will tell: Examining the potential effects of pre-arrest diversion efforts for drug offences using interrupted time-series analyses'.

To combat drug use and possession while reducing systemic social harm (e.g. conviction records and incarceration) some localised jurisdictions in England have made an effort to divert some of the lowest-level offences to treatment, away from system sanctions. In an effort to gauge the aggregate impact of pre-arrest (police-led) diversion, we employ a synthetic control design in an interrupted time series analysis. Relying on quarterly data over the last 10 years from several policing areas in England, we compare jurisdictions that engaged in a systematic diversion effort (e.g. West Midlands) to those that did not, while controlling for multiple factors on which the jurisdictions may differ (e.g. police workforce size, unemployment, population). The detectable impact of pre-arrest diversion on key outcomes and implications regarding police reported crime, cautions, and prosecutions are discussed.

Arrivals from 11.45am for a 12pm start. For those joining in-person, lunch will be served after the seminar from 1pm.
