Police use stop and search powers to search people who they suspect to be in possession of unlawful items, such as illegal drugs, weapons, or stolen property. The power is seen by the police as a valuable tool in the fight against crime, both deterring offenders and preventing further offending. However the evidence on its effectiveness is mixed, and there are gaps in the data, particularly surrounding its use in the UK context. Moreover, stop and search is associated with potential harm, both to individuals and to communities as a whole. This briefing will examine the current evidence in relation to stop and search and how it is practiced in the UK, examining in particular questions of its disproportionate use against young people and those from minority ethnic groups

  As Commissioners, we grounded our work every day in the memory of those whose lives were taken. Interacting with and learning from the individuals, families, and members of the communities most affected is an additional catalyst to the completion of our tasks. We have also been spurred on by the remarkable wisdom and generosity of everyone who contributed to our work: Participants and their counsel, witnesses (both through interviews and in public proceedings), experts, stakeholders, the media, community members, the wider public, and Commission staff. To all of you, we express our gratitude. This Report marks the end of our mandated responsibilities as a public inquiry and the shift to a shared responsibility to act. We do not absolve ourselves of obligations to contribute to the implementation of the Report’s recommendations in the days, weeks, and years to come. Yet acting on our recommendations is clearly in the hands and purview of others once the Commissioners have produced the Report. The leadership for this next phase includes those who participated in the Commission’s work; those external to the Commission, such as those who have reported on it and followed it; and others who have a formal, recognized duty to contribute to public safety and community well-being. We have said many times that this is a shared responsibility and opportunity. In Volume  6, Implementation, we expand on the importance of this collective responsibility, highlighting the significance of co-operation among politicians, policy-makers, institutions, organizations, community groups, and individuals right across society.

  This paper shows that shootings are predictable enough to be preventable. Using arrest and victimization records for almost 644,000 people from the Chicago Police Department, we train a machine learning model to predict the risk of being shot in the next 18 months. Out-of-sample accuracy is strikingly high: of the 500 people with the highest predicted risk, almost 13 percent are shot within 18 months, a rate 128 times higher than the average Chicagoan. A central concern is that algorithms may “bake in” bias found in police data, overestimating risk for people likelier to interact with police conditional on their behavior. We show that Black male victims more often have enough police contact to generate predictions. But those predictions are not, on average, inflated; the demographic composition of predicted and actual shooting victims is almost identical. There are legal, ethical, and practical barriers to using these predictions to target law enforcement. But using them to target social services could have enormous preventive benefits: predictive accuracy among the top 500 people justifies spending up to $134,400 per person for an intervention that could cut the probability of being shot by half.

The last days of colonialism taught America’s revolutionaries that soldiers in the streets bring conflict and tyranny. As a result, our country has generally worked to keep the military out of law enforcement. But according to investigative reporter Radley Balko, over the last several decades, America’s cops have increasingly come to resemble ground troops. The consequences have been dire: the home is no longer a place of sanctuary, the Fourth Amendment has been gutted, and police today have been conditioned to see the citizens they serve as an other—an enemy.

Today’s armored-up policemen are a far cry from the constables of early America. The unrest of the 1960s brought about the invention of the SWAT unit—which in turn led to the debut of military tactics in the ranks of police officers. Nixon’s War on Drugs, Reagan’s War on Poverty, Clinton’s COPS program, the post–9/11 security state under Bush and Obama: by degrees, each of these innovations expanded and empowered police forces, always at the expense of civil liberties. And these are just four among a slew of reckless programs.

  In Rise of the Warrior Cop, Balko shows how politicians’ ill-considered policies and relentless declarations of war against vague enemies like crime, drugs, and terror have blurred the distinction between cop and soldier. His fascinating, frightening narrative shows how over a generation, a creeping battlefield mentality has isolated and alienated American police officers and put them on a collision course with the values of a free society.Description text goes here

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.

This report examines the weapons and equipment generally at the disposal of law enforcement officers in several countries around the world. It also provides, for each of these countries, a brief overview of the rules governing the use of weapons by law enforcement officers. Precise and reliable information on the weapons and equipment of some countries’ police forces was often difficult to find. Nevertheless, certain interesting facts and patterns emerged from the Law Library’s research.

Research Summary: In this article, we argue that situ- ational crime prevention (SCP) strategies can be used to prevent public mass violence, as well as to mitigate the harms caused from those attacks that still occur. We draw from the SCP perspective generally, and its application to terrorism particularly, as well as from the public mass violence literature. We focus on the pillars of opportunity that include target selection, weapon selection, tools used, and conditions that facilitate public mass violence attacks.

Policy Implications: We conclude that SCP’s EVIL DONE risk assessment template could be refined for the public mass violence context. We argue that the exposed, occupied, nearer, and easy dimensions, along with a newly created personal grievance dimension, could be used to identify more at-risk settings that should receive more situational interventions to prevent these attacks. We similarly conclude that SCP’s other pillars could be used to prevent these attacks. We outline specific hard and soft interventions that could thwart these attacks. Importantly, we use examples to illustrate that SCP’s strategies could effectively mitigate the harms caused by public mass violence attacks that do occur. We also set forth research strategies to test our claims.
