John S. Hollywood is a senior operations researcher at the RAND Corporation and a professor of policy analysis at Pardee RAND Graduate School. He conducts decision science and systems engineering-related research in the areas of criminal justice, homeland security, and information technology.  He recently served as the director of the NLECTC Information and Geospatial Technologies Center, which provided strategic planning, technology research and assessment, liaison and outreach support on information technology and analytics for the National Institute of Justice. Other recent projects include leading a technology evaluation at a major active shooting exercise in Grand Central Terminal; leading numerous panels to determine science and technology-related needs for the Departments of Justice and Homeland Security; co-leading a multi-year evaluation of predictive policing experiments; characterizing recent US terror plots and how they have been foiled; identifying and characterizing scientific breakthroughs as evidenced in patent applications; developing tools to predict areas at risk of increased crime using criminal incident and suspicious activity data; and development of methods for fusing disparate reports about potential terrorist threats. He is a recognized expert on predictive policing and criminal justice technology and is commonly interviewed on these topics. He has written opinion pieces on best practices in counterterrorism and law enforcement technology for CNN, The Charlotte Observer, Crane's Chicago Business, Government Technology, and ORMS Today.

    CPD's 'Heat List' and the Dilemma of Predictive Policing

    Predictive policing — the use of computer models to identify areas or people at greater risk of being involved in a serious crime — is yielding results for police. How authorities plan to respond to the data is key.

    Predictive Policing: An Effective Tool, but Not a Crystal Ball

    Predictive policing is not an end-all solution, but rather a tool that must be used in concert with other policing resources as part of a broader anti-crime effort. Used properly, predictive policing can predict the risk of future events, but not the events themselves.

  • Can You Help Stop Terror Plots?

    Of the plots foiled in the last 10 years on U.S. soil, the would-be terrorists came from many different ethnic groups. We know of no cases where ethnic profiling helped stop a terrorist plot, write John Hollywood and Kevin J. Strom.

  • Alert Public and Cops Foiled the Most Terrorism Schemes

    The recent foiled plot by a naturalized citizen to bomb Washington-area metro stations has national counterterrorism officials warning that the U.S. faces not only risks from abroad, but also homegrown terrorism, write John S. Hollywood and Kevin J. Strom.
