NCHRP Research Report 1111/BTSCRP Research Report 12 presents a toolbox to help highway safety practitioners diagnose contributing factors leading to crashes for use in selecting appropriate countermeasures. To develop this toolbox, the research team conducted a systematic literature review; developed comprehensive evaluation and analysis procedures, methods, and tools; and conducted a workshop to demonstrate the use of the draft toolbox to receive feedback from practitioners. This publication will be of interest to state departments of transportation and other stakeholders concerned with diagnosing contributing factors leading to crashes for use in selecting appropriate countermeasures.

Anonymous tip lines (sometimes referred to as Anonymous Reporting Systems or ARS) have been recommended as promising and viable approaches to prevent school violence (e.g., Schwartz et al., 2016) and are becoming a popular mechanism for school systems to elicit information from students about potentially harmful events that may occur on school campuses (Planty et al., 2018). A recent national review found that 51% of middle and high schools reported having tip lines (Planty et al., 2020) and that 15 states have codified the use of tip lines through state legislation (Gourdet et al, 2021). The tip lines allow students to report suspicious behaviors they observe or become aware of (e.g., weapons in schools and planned school attacks), health and mental health concerns about their peers or themselves (e.g., depression or suicidal ideation), and other threats to the safety and well-being of students (e.g., bullying, cyberbullying, and physical fights). The idea is that providing students with an anonymous or confidential tool to report potentially harmful events to trusted adults, will lead to the prevention of the events before they occur or the mitigation of events that are already occurring. Tip lines include three primary components believed to be critical for school and community safety: 1) a mechanism for reporting behaviors that have been observed by others; 2) a mechanism for sharing that information within the confines of the law; and 3) encouragement for reporting (Amman et al., 2017; Vossekuil et al., 2002).

In an effort to combat contraband cell phones in correctional facilities, which have been found to challenge the safety and security of prisons and jails, correctional leaders and policymakers have employed a variety of technological and nontechnological strategies to find and remove these devices from their facilities. This practitioner-focused report examines one such contraband interdiction strategy: the use of cell phone detection canines (K9s). Historically, agencies have largely used K9s for perimeter patrol, crowd control, escapee apprehension, and drug detection in correctional settings, but more recently, agencies have trained K9s to detect contraband cell phones and other electronic storage devices.

  After a long period of continuous violent-crime declines throughout the U.S.—spanning from the mid-1990s through the early 2010s—many American cities are now seeing significant increases in violence. Nationally, in 2015 and 2016, murders rose nearly 11% and 8%, respectively. The national homicide rate declined slightly in 2017 and 2018, before ticking upward in 2019. In 2020, the nation saw its largest single-year spike in homicides in at least 100 years—which was followed by another increase in murders in 2021, according to CDC data and FBI estimates. In the last few years, a number of cities have seen murders hit an all-time high. In addition to homicides, the risk of other types of violent victimizations rose significantly, as well. While various analyses estimated a slight decline in homicides for the country in 2022, many American cities still find themselves dealing with levels of violence far higher than they were a decade ago. While violent crime—particularly murder—is the most serious due in large part to its social costs, there have also been worrying increases in crimes such as retail theft, carjacking, and auto theft, as well as in other visible signs of disorder in public spaces (from open-air drug use and public urination to illegal street racing and large-scale looting and riots). Although several contributing factors are likely, this general deterioration in public safety and order was unquestionably preceded and accompanied by a virtually unidirectional shift toward leniency and away from accountability in the policing, prosecutorial, and criminal-justice policy spaces. That shift is evidenced by, among other things, three major trends in enforcement: • A 25% decline in the number of those imprisoned during 2011–2212 • A 15% decline in the number of those held in jail during 2010–211 • A 26% decline in the number of arrests effected by law-enforcement officers during 2009–1914 Notable contributing factors to the decline in enforcement include: • A sharp uptick in public scrutiny and interventions—in the form of investigations and legal action taken by state attorneys general and the federal Department of Justice—against local law-enforcement agencies • The worsening of an ongoing police recruitment and retention crisis, particularly in large urban departments • The electoral success of the so-called progressive prosecutor movement, which, by 2022, had won seats in 75 jurisdictions, representing more than 72 million U.S. residents • Perhaps most important, the adoption of a slew of criminal-justice and policing reform measures at all levels of government Those who are skeptical of the criminal-justice reform movement have devoted most of their efforts to arguing against the movement’s excesses and explaining why it would be unwise to enact certain measures. Less effort has been devoted to the extremely important task of articulating a positive agenda for regaining what has been lost on the safety and order front. This paper seeks to add to that positive agenda for safety by proposing three model policies that, if adopted, would help, directly and indirectly, stem the tide of rising crime and violence, primarily by maximizing the benefits that attend the incapacitation of serious criminals (especially repeat offenders) and by encouraging the collection and public reporting of data that can inform the public about the downside risks that are glossed over by decarceration and depolicing activists ....
