Project Servator is a strategic method of policing designed to deter, detect and disrupt a wide range of criminal activity including terrorism. This paper is the first empirical study to evaluate the stop and search aspect of Servator deployments. We compare the outcomes of 3488 routine stop and searches and 510 Servator stop and searches to determine whether the stop and search tactics used in this initiative produce more positive outcomes than routine stop and searches. We also compare outcomes of stop and searches that occurred on the basis of suspicious behaviour alone, by ethnicity, and through using a geographically matched sample. Collectively, the results indicate that stop and searches that occur during Servator deployments are more efficient than routine stop and search.

British policing, and the criminal justice system more widely, is in crisis. Great swathes of the public believe that those who commit crimes do not suffer sufficient consequences for their actions.1 They witness police officers being told to consider making fewer arrests,2 and a low likelihood of offenders being charged or summonsed to court.3 When they look at the criminal courts, the public see huge delays4 and lenient sentences for those that have broken the law.5 The public observe individuals in their neighbourhoods continuing a life of crime, when they should be in prison. There is a significant distance between how tough on crime and criminals the public believe the police and criminal justice system should be, and how tough on crime and criminals the public believe the police and criminal justice system currently are. We call this the ‘Toughness Gap’. And this is not just about public perception. While overall crime may have fallen over the 30 years, this headline obscures an explosion in many types of crime – including an increase in criminal offences by 12% over the last year alone.6 Robbery increased from 62,354 offences in 2021 to 82,437 in the year to September 2024.7 Knife crime increased by 88.6% between 2015 and 2024.8 Police recorded incidents of shoplifting increased by 23% between 2023 and the year to September 2024 – the highest levels since current records began over 20 years ago.9 Fraud increased by 19% over the last year.10 Between 2010 and 2018 over 70% of police stations in London were closed.11 Between 2010 and 2017 the number of police officers in England and Wales was cut by 19%, before a rapid recruitment exercise replaced some of the officers lost.12 By 2024 the number of police officers was still 3% below 2010 levels.13 As part of its ‘A Portrait of Modern Britain’ project, Policy Exchange commissioned exclusive polling on the views of the British public across a wide range of areas – including on crime and policing. This report reveals that a distinctive electoral battleground has opened on crime and policing. We reveal two key trends. (i) Firstly, there is a clear mandate for the police to adopt a tougher approach to crime than they are currently perceived to be taking. This finding is observed across every major demographic group (age, sex, ethnicity), every economic grouping and amongst supporters of every political party. (ii) Secondly, Reform UK is establishing itself as the political home for those who are most likely to be dissatisfied with policing and those who believe there is the greatest gap between how tough olicing should be and how tough policing currently is. These two trends come with lessons and warnings for other political parties – particularly the incumbent Labour Government.

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

Police “stop-and-frisks” of pedestrians and motorists have become an increasingly controversial tactic, given low average rates of contraband discovery, incidents of abuse, and evidence of racial disparity. Study of the tactic by economists has been much influenced by Knowles, Persico, and Todd (2001; hereafter, KPT) who first suggested the use of a “hit rate” (contraband discovery rate per frisk) test to distinguish racial prejudice from statistical discrimination in highway searches by police officers. Models used by KPT and almost all subsequent literature (e.g., Anwar and Fang 2006) on the subject imply diminishing marginal returns to frisks. That is, if frisks decrease substantially, the rate of contraband discovery should rise, ceteris paribus. This is the first paper to test this assumption empirically using arguably exogenous variations in frisk rates (cf. Feigenberg and Miller 2022). 1 We study the period around the nationwide protests that followed the killing of George Floyd on May 25, 2020, after which police frisks dropped tremendously and rapidly. Using extremely granular data from Chicago, we find that hit rates increased as police frisks plunged, in line with the predictions of KPT.

It is irrefutable that citizens should enjoy freedom of movement and an expectation of an uninterrupted private life; these protections underpin our democracy and uphold our fundamental human rights. These expectations are acutely relevant to the use of stop and search and it is essential that all powers exercised by the police are used lawfully, only when necessary and are proportionate, but more importantly, that they are seen to be so. The assessment and recommendations set out in this report provide a valuable commentary on the expectations communities have as to how the police should operate when tackling violent crime and upholding the law, as well as providing an important reminder that policing is underpinned by public consent. As well as providing a constructive interpretation on the value of stop and search powers and the importance of active monitoring arrangements, the report provides helpful examples of where police forces and communities have successfully come together to stimulate improvements in police operational activity as well as promote confidence that officers are acting in the public interest and with proper regard to the Codes of Conduct that govern their powers and the use of force.

  It is widely accepted that policing is most effective when it secures the co-operation, trust, and confidence of the public. The police themselves recognise that these features are critical to their relationship with the public and form an important part of their day-to-day working culture. This co-operation, trust and confidence is being undermined by unfair and disproportionate stop and search practices. Such practices cause alarm and distress to members of the public, damage trust and confidence in policing, and make the police’s job more difficult overall. We therefore believe that due to the harms outlined in this report, the government must urgently repeal the harmful s.60 police power and instead invest in working with communities to improve trust and confidence and tackle the root causes of violent crime. Furthermore, insufficient scrutiny of stop and search powers means that the police are not effectively being held to account where there is evidence of unfair and discriminatory use of these powers. Fair and effective community scrutiny for all police forces should be mandated, adequately resourced and supported by an independent national body. Section 60 (s.60) of the Criminal Justice and Public Order (CJPO) Act 1994 allows a constable in uniform to stop and search any pedestrian, or any vehicle for offensive weapons or dangerous instruments. This legislation was originally introduced to tackle football hooliganism and the threat of serious violence at football games. Today, s.60 permits officers to search a person or vehicle in anticipation of violence if an officer of or above…..

In our previous research, focusing on adults, we found that despite support for the use of stop and search powers in principle, there were deep misgivings among Black adults about the way stop and search was carried out in practice, as well as the general service and treatment they received from the police. For Black children, these misgivings were amplified. They have less trust in the police than children from every other ethnic group, and less trust than Black adults do. This report, which is the second of three publications related to our research project, focuses specifically on the views of children and teenagers. It is based on findings from three focus groups with predominantly Black or Black and Mixed ethnicity children, and a survey of 1,542 ten to 18 year olds, 100 of whom were Black.

In recent years, the police use of stop and search powers has become a totemic issue - many have argued that it is the main (or primary) cause of low confidence among Black communities in the UK, when compared to the rest of the population. However, our research, which draws on the most comprehensive survey of Black adults’ views about policing ever conducted in England and Wales, suggests that Black people’s concerns about the use of stop and search cannot be viewed in isolation; instead their attitudes towards its use by the police are shaped by, and closely connected to, their experience of policing as a whole. Black adults expressed at least as much concern about a perceived failure by policing to get ‘the basics’ right for their communities, such as responding to emergencies, investigating crime and engaging with victims, as they did about the use of stop and search. This report, which is the first of three publications related to this research, and specifically focuses on the views of adults.
