Methodological Rigor: Moderate- time series

Abstract: (from NCJRS) This paper adds to a growing body of research which explores the relationship between aggressive police strategies and serious crime. For one month, police enforced disorder crime in a small section of one community. An interrupted time series analysis was utilized to evaluate the effects of this intervention on robbery and aggravated burglary in a target area and a control area. The strategy was found to be unrelated to levels of aggravated burglary and robbery in the target area. There was no spatial displacement of crime. Explanations for the findings are offered.
