What This Document Is
These are class notes from CCJ 3701, Research Methods in Criminal Justice at Florida Gulf Coast University. The notes focus on factors impacting the reliability of eyewitness identification – a critical component of many criminal investigations and legal proceedings. It categorizes these factors as either “estimator variables” (things the justice system *cannot* control) or “system variables” (things the justice system *can* control) to improve accuracy.
Why This Document Matters
This document is essential for criminal justice students, legal professionals, and anyone interested in understanding the complexities of eyewitness testimony. It’s used when studying the scientific basis of evidence and the potential for error in the justice system. Understanding these variables is crucial for evaluating the strength of evidence presented in court and for developing best practices in investigative procedures. The notes highlight recent court rulings and ongoing research in this area.
Common Limitations or Challenges
These notes provide an overview of research findings, but do not offer definitive answers. The science of memory is complex, and the impact of these variables can vary significantly depending on the specific circumstances of a case. This document does not provide legal advice or a complete guide to courtroom procedure. It also doesn’t cover all possible factors influencing eyewitness reliability.
What This Document Provides
This document details several key estimator variables, including weapon focus, duration of observation, distance and lighting, witness characteristics (age, intoxication), perpetrator characteristics (disguises), memory decay, and race bias. It also outlines system variables such as lineup construction, blind administration, avoiding feedback, recording confidence levels, and the potential issues with multiple viewings (mugshot exposure). The notes also reference a court directive regarding questioning witnesses about discussions with co-witnesses and recording those discussions.
This preview does *not* include specific research methodologies, statistical analyses, or detailed case studies. It does not provide a comprehensive list of all relevant legal precedents.
