Study Notes
Introduction to Law and Science
- Criminal justice system protects the innocent and ensures the truth emerges
- Law defines criminal behavior and sets standards of evidence for prosecution
- Law relies on the adversarial system, while science relies on scientific methodology
- Law seeks to settle disputes, while science describes the natural world
Forensic Science
- The term 'forensic' originates from the Latin "forensis," meaning public debate or discussion, with judicial connotations
- "Science" comes from the Latin word for knowledge and relates to the scientific method
- Forensic methodologies encompass a wide range of disciplines, making forensic science hard to define
- Broadly, forensic science involves the application of scientific knowledge and techniques to legal matters
Importance of Forensic Science
- Forensic science assists in criminal investigations by identifying suspects, providing timelines, establishing presence, determining details of the crime, and identifying the quantity of suspects
- Science brings objectivity to investigations, reducing influence of emotion, bias, and opinion
- Subjective evidence, once prominent, has been replaced with more objective scientific evidence
Forensic Scientists
- Forensic scientists act as unbiased advocates for objective facts
- They may be called upon as expert witnesses, designated by a judge
- Lay witnesses provide factual testimony based on personal experience, not expertise
- Expert witnesses offer opinions based on their knowledge and findings, having a significant impact on legal cases
- Expert witness criteria include integrity, training, experience, and adherence to established scientific principles, including peer review, testing, and validation, error rates, and general acceptance
Scientific Method
- Ensures scientific integrity through strict guidelines
- Consists of observation, measurement, experimentation, hypothesis formulation, testing, and modification
- Hypotheses validated through experimentation become suitable evidence
Crime Scene Investigation
- Involves the identification, collection, and preservation of evidence
- Forensic science professionals conduct scientific analysis on evidence gathered at the crime scene
- In Canada, crime scene investigators are called Forensic Identification Officers
Crime Scene Investigation: Methodology and Principles
- Crime scene investigation is a methodical process that follows established principles and procedures
- The process is dynamic and thoughtful, requiring a proactive approach to link pieces of evidence and utilize experience and observation
- Rooted in the scientific method
Objectives of Crime Scene Investigation
- Recognize and identify forensic evidence
- Collect and preserve evidence
- Reconstruct the crime
- Develop theories about the crime, such as outlining event sequences, motives, etc.
The CSI Effect
- Unrealistic expectations of forensic science and crime scene investigation capabilities, fueled by media portrayal
- A phenomenon that dates back to the 'Sherlock Holmes Effect'
- Media inaccurately depicts roles, responsibilities, capabilities, evidence types, procedures, and timelines
Examining the CSI Effect
- The CSI Effect portrays forensic science as central to investigations, unlike other shows that depict forensics as a part of a broader criminal justice system
- Focuses on the collection and analysis of forensic evidence
Impact of the CSI Effect
- Impact on the court and legal system:
- Influence on jurors
- Potential impact on prosecution and defense strategies, possibly contributing to higher acquittal and conviction rates
- Potential impact on criminal activity:
- May inadvertently educate current or prospective criminals
