Criminal Reduction Utilising Statistical History is an IBM predictive analytics system that attempts to predict the location of future crimes.[1] It was developed as part of the Blue CRUSH program in conjunction with Memphis Police Department and the University of Memphis Criminology and Research department.[2] In Memphis it was “credited as a key factor behind a 31 per cent fall in crime and 15 per cent drop in violent crime.”[3]
, it was being trialed by two British police forces.[1]
In 2014 a modified version of the system, called CRASH (Crash Reduction Analysing Statistical History) became operational in Tennessee aimed at preventing vehicle accidents.[4]
