This case study examined the effect of the Columbine High School Massacre on a pretrial services unit, stating that the massacre decreased intakes into the jail, increased the proportion of persons detained for violent crimes, and made bond commissioners less willing to facilitate the release of persons arrested for violent crimes. It argues that pretrial release rates for domestic and other violence-related cases were not affected. In the case study, implications for situational criminological theory and criminal justice system policy are discussed as well.
