"The rapid growth of the 'place and crime' literature has demonstrated the need for proactive police strategies in crime hotspots. Research consistently finds that most crime is concentrated at relatively few addresses and that these places tend to remain 'hot' consistently over time (Sherman, Gartin, & Buerger, 1989; Weisburd, et. al., 2004). Today, some of the discussion has shifted to determining what strategies can best accommodate crime problems at these locations. With the advent of new technologies, researchers have begun examining whether closed-circuit television (CCTV) cameras exert a significant deterrent effect at crime hot spots. In 2016, Detroit began the 'Green Light' initiative by outfitting businesses with CCTV cameras connected live to their computer-aided dispatch system. Utilizing the start of the Detroit Green Light initiative in 2016, this study examines 86 business that joined the Green Light program between January 1, 2016 and December 31, 2016, compared to a matched sample of businesses that did not. Using hierarchical linear models and Bayesian inference, this study assesses the impact of the Green Light program on violent crime, property crime, disorder crime, and calls for service in and around the immediate vicinity of businesses. A cost-benefit analysis of the program determines whether the program is a cost-effective method of crime reduction."--Page ii.
