Routine activity theory

Routine activity theory, developed by Marcus Felson and Lawrence Cohen, draws upon control theories and explains crime in terms of crime opportunities that occur in everyday life. A crime opportunity requires that elements converge in time and place including a motivated offender, suitable target or victim, and lack of a capable guardian. A guardian at a place, such as a street, could include security guards or even ordinary pedestrians who would witness the criminal act and possibly intervene or report it to law enforcement. Routine activity theory was expanded by John Eck, who added a fourth element of "place manager" such as rental property managers who can take nuisance abatement measures.
