Twenty five years ago, US criminologist Lawrence Sherman wryly asked: “If future crime is six times more predictable by the address of its occurrence than by the identity of the offender, why aren’t we thinking more about wheredunit, rather than just whodunit?” (Sherman, 1995, pp. 36–37). Many empirical observations that crimes of various kinds are more likely to occur in particular places, and at particular times, have since led to significant reductions in the incidence of specific crimes, ranging from bicycle theft to residential burglaries, to assaults in and around bars, to armed robbery, and so on (see e.g. Wortley & Townsley, 2016). Analysing and responding to the spatial and temporal dimensions of specific kinds of crime is now commonplace among crime prevention agents and practitioners.
