"In 2006, the National Institute of Justice funded RTI [Response to Intervention] International to develop and test a process for analyzing and prioritizing data from one type of SAR [Suspicious Activity Report]: 911 calls for service. As part of that project, RTI researchers (including the authors of this article), in collaboration with the Washington, D.C., Metropolitan Police Department, analyzed more than 1.3 million 911 MPD call records. The main goal of our study was not to identify confirmed terrorist activity. Rather, we designed and tested a process for reducing a large volume of data to a smaller subset of incidents that could then be reviewed for follow-up investigation. Our study showed that simple analytic processes could produce operationally relevant findings from 911 calls. We documented this process so it could be implemented and refined in other jurisdictions."
