Calls for police reform play an integral part in the evolution of modern policing. But what truly needs reform is how police agencies evaluate their performance. Rather than determining effectiveness exclusively through crime-fighting statistics, police agencies must also incorporate assessments of how community members are treated. Evidence-based policing must acknowledge a large body of research on procedural justice and recognize the critical role it plays in determining police legitimacy. To implement effective reforms within this framework, the definition of “good policing” must be reimagined, as well as the metrics used to evaluate it. This Ideas in American Policing essay examines previous reform concepts and their shortfalls. It explores how human behavior is heavily influenced by incentives and disincentives and whether a strong enough reward system is in place to truly move officers from the “warrior” to the “guardian” mentality. Lastly, it examines what police leaders, government officials, and policing scholars will need to do to implement, successfully evaluate, and achieve lasting reform within the communities being served.

The government’s Safer Streets mission aims to reduce serious harm and increase public confidence in policing and the wider criminal justice system. This guide supports senior police leaders and police and crime commissioners to help achieve this mission. It clearly sets out the best available evidence on public confidence in the police, as well as the policing activities that are most likely to have an impact. „ Implementing neighbourhood policing – Having a targeted visible presence in crime and anti-social behaviour hot spots or places with low trust. – Community engagement to identify the crime and anti-social behaviour issues that matter to people locally. – Carrying out effective problem-solving to tackle the issues that matter the most to local people. „ Policing with procedural and distributive justice – Making fair decisions and treating people respectfully. – Not being seen to over-police and under-protect communities. „ Improving police contact with victims – Responding to the needs and concerns of victims. – Focusing as much on the process as the end result. „ Improving police contact with suspects – Minimising the number of negative experiences. – Explaining enforcement action and preserving people’s dignity. „ Tackling police wrongdoing – Working within the law and adhering to ethical and professional standards. The guide begins by providing key definitions and trends in public perceptions over the past 20 years. It ends with a summary of what else may be important to public confidence in the police.

We study the prevalence and effects of individuals with past criminal charges among candidates and elected politicians in Brazil. Individuals with past criminal charges are twice as likely to both run for office and be elected compared to other individuals. This pattern persists across political parties and government levels, even when controlling for a broad set of observable characteristics. Randomized anti-corruption audits reduce the share of mayors with criminal records, but only when conducted in election years. Using a regression discontinuity design focusing on close elections, we demonstrate that the election of mayors with criminal backgrounds leads to higher rates of underweight births and infant mortality. Additionally, there is an increase in political patronage, particularly in the health sector, which is consistent with the negative impacts on local public health outcomes.
