Using analytics to fight crime before it happens
A decade ago, crime in Memphis trended above record highs. The Memphis Police Department developed an analytics platform that created multilayer maps and spreadsheets to systematically identify and verify patterns of criminal activity. That helped the Precinct Commanders focus resources in hotspots on the right days of the week at the right time of day. Visualizing these patterns enhanced officers’ long-standing knowledge about where, when and how violent crime takes place. The police department changed its patrolling strategy as a result— and reduced crime by 24 percent.
