Study Notes
Forensic Science Overview
- Forensic science integrates scientific principles with crime investigation to uncover legal truths.
- It operates within an adversarial system, differing from the scientific method, emphasizing equal representation during legal proceedings.
Basic Concepts of Forensic Chemistry
- Questioned Sample: Analyzing a sample with an unknown identity.
- Known Sample: A sample with established identity and origin, used as a reference.
- Evidence: Facts or information that support the validity of a belief or proposition.
- Scientific Method: A systematic approach to acquire knowledge through observation and experimentation.
Theories of Forensic Chemistry
- Forensic chemists utilize the scientific method to analyze evidence from crime scenes.
- Questioned samples must be compared to known samples to establish identity or origin.
- Known samples can include evidence like hair collected from suspects.
Roles of Forensic Chemists
- Primarily analyze evidence in a crime lab rather than the crime scene.
- Collaborate as part of a team of specialists; do not directly solve crimes but provide analytical support.
- Analyze trace evidence and controlled substances to identify unknown materials and quantify drugs.
- Follow strict protocols for evidence handling and documentation to ensure reliability.
Challenges Faced by Forensic Chemists
- Must manage pressure from law enforcement for rapid results while maintaining accuracy.
- Require strong communication skills for courtroom testimony, especially during cross-examinations.
Rules in the Practice of Forensic Chemistry
- Go Slowly: Prioritize thorough work over speed; adjourn cases rather than rush results.
- Be Thorough: Conduct comprehensive examinations and prefer quantitative analyses when possible.
- Take Notes: Maintain clear, organized records of all observations and findings.
- Consult Others: Seek advice and insights when encountering unfamiliar situations or complexities.
- Use Imagination: Employ a disciplined imagination for hypotheses and inferences but maintain objectivity in reporting.
