TL;DR: In this article, the authors examined the distribution of crime at street segments in Seattle, Washington, over a 14-year period and found that a relatively small proportion of places belong to groups with steeply rising or declining crime trajectories and that these places are primarily responsible for overall city trends in crime.

TL;DR: In this article, the authors examined the relationship between research design and study outcomes in a broad review of research evidence on crime and justice commissioned by the National Institute of Justice and found that design does have a systematic effect on outcomes in criminal justice studies.

TL;DR: The Evidence-Based Policing Matrix as mentioned in this paper is a translation tool that categorizes and visually bins all experimental and quasi-experimental research on police and crime reduction into intersections between three common dimensions of crime prevention: the nature of the target, the extent to which the strategy is proactive or reactive, and the specificity or generality of the strategy.

TL;DR: The findings dramatically emphasize the need for government leaders, policy makers, researchers, and funding agencies to support both outcome evaluations of these programs as well as efforts to develop an infrastructure to foster counter-terrorism evaluation research.

TL;DR: In this article, a mathematical model of the distribution of criminal opportunities and offender decision making on which of those opportunities to victimize is presented, where criminal opportunities are characterized in terms of the risk of apprehension that attends their victimization.
