Research Compendium
The Research Collection
The collections are designed to work together. Reports present EWRL's original analysis. Data provides the empirical foundation. The Evidence Base, Law & Policy, and Bulletins supply the research, legal, and operational context. The Annotated Bibliography and Table of Authorities provide the underlying source material, while Methods documents how the research is produced and interpreted.

Reports
Original, versioned EWRL research drawing on incident data, legal authority, and the wider evidence base. Use Reports for the Lab's full analyses, findings, and conclusions on specific research questions.
Browse ReportsData
Aggregate incident data from the EWRL research dataset, with privacy suppression and interactive summaries of demographics, geography, encounter characteristics, tactics, and outcomes. Use Data to explore the underlying patterns behind EWRL findings.
Browse DataEvidence Base
Structured reviews of police intervention options, including less-lethal tools, lethal force, crisis resources, specialist capabilities, and tactical resources. Use the Evidence Base to understand what research supports, where findings are mixed, and what remains uncertain.
Browse Evidence BaseLaw & Policy
Backgrounders on constitutional standards, case law, statutory frameworks, civil liability, and policy issues relevant to edged-weapon critical incidents. Use Law & Policy to understand the legal rules that govern force, review, and accountability.
Browse Law & PolicyBulletins
Concise synthesis connecting research evidence, law and policy, and operational practice across the incident lifecycle. Use Bulletins for focused analysis of recurring issues that cut across multiple EWRL collections.
Browse BulletinsAnnotated Bibliography
A curated collection of leading research with annotations, DOI links, keyword tags, and summaries. Use the bibliography to trace EWRL claims back to the broader empirical literature and explore individual studies in greater depth.
Browse BibliographyTable of Authorities
Cases, statutes, and constitutional provisions cited across EWRL research, with summaries and cross-references to related content. Use the Table of Authorities to locate the legal sources underlying EWRL's analysis.
Browse Table of AuthoritiesMethods
Documentation of EWRL's data sources, inclusion criteria, coding rules, reliability procedures, statistical methods, suppression controls, versioning, and known limitations. Use Methods to understand how EWRL evidence is produced and how its findings should be interpreted.
