The present study examines the risk of citizens encountering police use of intermediate and deadly force, as opposed to using physical force, given a set of individual, situational and neighborhood variables.

The study uses data from 2003 to 2016 in the Dallas Open Data Portal. Two-level multinomial logistic regression is used to analyze the data.

The effects of citizen race differ across the types of police force. Overall, citizen race plays no significant role in the officer's decision to shoot firearms at citizens. However, there is evidence of intra-racial disparity in officer-involved shootings (OISs) between Hispanic citizens and officers. African American citizens are disproportionately exposed to display-but-don't shoot incidents, while Hispanic citizens have a lower risk of encountering police use of intermediate weapons.

The study helps to understand how citizen and officer race influence and interact across various types of police force. Implications of the results are offered in relation to relevant literature.

Knife crime and serious violent crime (SVC) among youth has been growing at an alarming rate in the UK (Harding and Allen, 2021). Community and school-based intervention and prevention services to tackle knife crime are being developed with some evaluation; however, these are independent and of varied quality and rigour. Therefore, the purpose of this study is to record the approaches being developed and synthesise existing evidence of the impact and effectiveness of programmes to reduce knife crime. In addition, the complex factors contributing to knife crime and SVC are discussed.

A systematic approach was used to conduct this knife crime intervention evidence review using two search engines and four databases. Inclusion and exclusion criteria were applied to ensure focus and relevance. The results of searches and decisions by the research team were recorded at each stage using Preferred Reporting Items for systematic reviews and meta-analyses (PRISMA).

Some evidence underpins the development of services to reduce knife crime. Much of the evidence comes from government funded project reports, intervention and prevention services reports, with few studies evaluating the efficacy of intervention programmes at present. Some studies that measured immediate impact in line with the programme’s aims were found and demonstrated positive results.

This systematic review specifically synthesised the evidence and data derived from knife crime and weapon carrying interventions and preventions, integrating both grey and published literature, with a novel discussion that highlights the importance of outcome evaluations and issues with measuring the success of individual level interventions and their contributions to the overall reduction of violence.
