How the study was done
The dissertation brings together civilian surveys, officer surveys and published executive statements to explore technology and bias in Florida policing. How those sources were collected matters to how we read the findings.
01 · The design
A Florida case, examined through people’s perspectives.
The dissertation describes a qualitative case study: an examination of how unconscious bias may affect the adoption and use of emerging law-enforcement technologies, and what that could mean for citizens’ security and privacy. Florida supplies the setting. Although the research sought perspectives from different parts of the state, it did not set out to compare geographic regions.
The design combines surveys and thematic analysis. Chapter Six also uses descriptive statistics to compare the civilian and officer responses. Counts show how these respondents answered; the sampling approach limits how far those patterns can be generalized.

02 · Recruitment and participation
A voluntary sample with eligibility checks.
The study used purposive sampling: it sought people whose roles or experiences were relevant to the research. The survey link was publicly available, with opening questions that screened for eligibility. The civilian recruitment description includes distribution through social media and excludes people directly affiliated with law enforcement. Participation was voluntary, rather than randomly assigned.
The civilian and officer surveys were administered through Qualtrics. The dissertation says the survey did not collect names or other identifying information. Its results chapters report the groups below; the executive material was a separate content analysis of published reports, speeches and interviews.
- 20civilian respondents15 living in Florida; 5 elsewhere
- 10officer respondentsAll current or past Florida law enforcement officers
- 20executive statementsPublished material analyzed separately

03 · The change in approach
Interviews were planned. Surveys became the way in.
The research initially called for in-person interviews. The dissertation reports that officers were reluctant to take part because of confidentiality and data-security concerns, including fears of professional consequences if their identities were exposed. The researcher shifted to an online survey format.
According to the dissertation, this improved participation but reduced the depth of insight that direct interviews might have provided. The format change is part of the study’s limitations, as well as part of its story.

04 · The analysis
From responses to codes, then themes.
Chapter Three describes a three-stage coding process. Coding means assigning labels to material so that patterns can be examined. The stages below summarize the process the dissertation reports.
Initial coding
Read civilian responses for emerging patterns, then compare them with officer responses to identify themes around the use of technology.
Focused coding
Narrow attention to material concerning unconscious bias and its possible influence on decisions about adopting and using technology.
Thematic analysis
Bring the codes together into broader themes, connect those themes to the research questions, and interpret the community implications.
Chapter Six compares the two survey groups using descriptive statistics and comparative measures. Chapter Seven separately examines published executive material, organizing it around acknowledgment of bias, types of bias, proposed solutions, public trust and perceptions of technology.
A qualification in the source. The methods account is not fully consistent about the survey format. Page 44 describes multiple-choice questions and open-ended prompts; page 51 describes the civilian survey as exclusively multiple choice. This summary preserves that difference. The coding stages above describe the dissertation’s stated method; they do not establish that every reported finding came from an open-ended answer.

05 · The theoretical frames
Technology acceptance and public legitimacy.
Technology Acceptance Model 2
TAM2 helps frame why officers might accept a tool. The dissertation discusses perceived usefulness alongside social expectations, voluntariness and professional image. These factors help organize its account of technology adoption.
Procedural Justice Theory
This frame concerns community trust, citizen rights and participation in decisions. The dissertation uses it to connect choices about technology with the public’s view of whether those choices are legitimate.

06 · Reading the limits
Who answered shapes what can be concluded.
The civilian sample was capped at twenty. Voluntary, purposive recruitment may leave out people who are unfamiliar with the technologies or hesitant to discuss them. Self-reported answers can also reflect what seems socially acceptable, or a person’s limited awareness of their own biases.
The dissertation acknowledges that its small sample and difficulty recruiting officers restrict generalization across agencies. It also identifies the loss of interview depth, rapidly changing technologies, limited literature, and some participants’ reluctance to engage because they associated predictive-policing research with disputes over diversity, equity and inclusion programs.
These limits matter when reading both agreement and disagreement between the groups. The dissertation calls for larger, more diverse samples and approaches that make participation feel more secure.

About this presentation
This is attributed commentary on Dr. Trei McMullen’s research. The research, its design and its findings are his. The dissertation’s author was not involved in producing this presentation.
The passages marked Explainer commentary throughout the deck, and the article in the reader, are the work of Scott W. Waddell, D.S.I., who decided what this presentation says and is responsible for it. The article’s own byline and identifier appear inside the reader.
Every factual slide carries the printed pages of the dissertation that support it. The deck was built only from the accepted explainer article and the dissertation itself; nothing was added from any other source, and no statement here is stronger than the one the dissertation makes.
Workspace evidence for this section, rather than dissertation pages: the project brief §8 and the commentary scope and byline decisions recorded in the project’s decision register.
The officers the study most needed to hear from did not trust that their own words could be kept private.
