Policing Directions: A Systematic Review on the Effectiveness of Quantitative Police Presence

By Philipp M. Dau, Christophe Vandeviver, Maite Dewinter, Frank Witlox, Tom Vander Beken

We systematically review the effectiveness of police presence. In doing so, we investigate concepts of police presence and differences between reported effects. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and protocols, we systematically identify and review eligible studies on police presence. Further, quality assessment and findings synthesis are used to map limitations of current research as well as grounds for future avenues. The systematic search strategies yielded 49 studies focusing on testing the effects of police presence or evaluating its measurement. We find evidence that police presence has mostly crime reduction effects on crimes related to motor theft, property, violence, and guns. Police presence also reduces calls for service and improves traffic behaviour. Police presence focused on specific areas, times, and types of crime achieves maximum effectiveness. The reviewed studies show a high degree of heterogeneity in reporting, however, which limits comparability of findings across studies. Research on police presence presents evidence for significant crime preventative effects of focused police actions. Police presence shows the strongest effects when focused on certain areas, times, or types of crimes. We encourage future research to focus on police presence en route and its effects, including crime prevention, traffic regulation, and fear of crime.

Finding the Police Before the Police Find Them? Investigating How and Why Motorists Use Facebook for Knowledge of Roadside Drug Testing Locations

By Laura Mills, James Freeman, and Verity Truelove

Facebook groups and pages exist that expose the locations of roadside drug testing, potentially undermining police enforcement and enabling punishment avoidance. This study aimed to understand how and why these sites are used, with a focus on Queensland motorists who reported using illicit drugs and/or medical cannabis and used Facebook police location communities. Interviews with 30 participants were conducted. A thematic analysis revealed that participants used police location communities to avoid receiving a charge for driving under the influence of drugs. Upon observation of a relevant roadside drug-testing location on police location communities, participants reported (a) delaying their driving and/or (b) circumventing the operation. Avoidance of roadside drug-testing locations appeared driven by the perception that laws for driving under the influence of drugs were unfair and that a charge for driving under the influence of drugs would negatively impact their life. The findings provide important knowledge regarding police location communities and have implications for how roadside drug testing could be most effectively operated.

Hardening the System: Three Commonsense Measures to Help Keep Crime at Bay

By Rafael A. Mangual

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 2010–2113 • 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.

Enforcement Strategies for Fentanyl and other Synthetic Opioids

The synthetic opioid crisis in North America has increased fatal overdose rates to unprecedented levels within a matter of a few years. It involves new technologies, a new source of supply (the chemical industry in China), and new forms of distribution (the internet and mail). These elements are perhaps even more difficult to suppress than other supply sources from foreign countries. This has led to an assumption that nothing can be learned from prior experience in trying to control drug markets.

This paper applies the insights of the “focused deterrence” approach developed by David Kennedy and Mark Kleiman, which involves using multiple levers to attain a specific policy goal. We conclude with some specific suggestions for local and national supply-control agencies— including the need to focus more on regulating rather than reducing markets to minimize harm, and to distinguish between markets not yet swamped by fentanyl or in transition and those where the drug is entrenched. Strategies appropriate in one context may not serve well in another.

An Assessment of the Tackling Knives and Serious Youth Violence Action Programme (TKAP) - phase ll

By Liz Ward, Sian Nicholas and Maria Willoughby

The Tackling Knives Action Programme (TKAP) ran initially from June 2008 until March 2009 and aimed to reduce teenage knife crime in ten police force areas in England and Wales. TKAP Phase II was then launched and the programme re-branded into the Tackling Knives and Serious Youth Violence Action Programme. Phase II ran from April 2009 to March 2010 in 16 police force areas (the original ten TKAP forces and six new areas)1 and aimed to reduce all serious violence involving 13- to 24-year-olds using a range of enforcement, education and prevention initiatives.

The Punishment and Prevention of Crime

By Edmund F. Du Cane.

“This vintage book contains a detailed treatise on the history and development of punishment and crime prevention. It explores how the ideas concerning crime and how to deal with it have changed throughout the ages, as well as analysing the way that we deal with such behavior in modern society. A thought-provoking and insightful volume, "The Punishment and Prevention of Crime" is highly recommended for those with an interest in sociology and the concepts of punishment and rehabilitation. Contents include: "Criminals and Punishments", "Punishments in the Middle Ages-Capital Executions", "Gaols in Former Times", "Modern Prisons", "Transportation", "Penal Servitude", "Supervision-Discharged Prisoners' and Societies", "The Prevention System-Juveniles-Reformatories-Industrial Schools", et cetera. Many vintage books such as this are increasingly scarce and expensive.” (From Amazon).
