Study Notes
Introduction to Forensic Science
- Forensic science applies scientific methods to investigate legal issues.
- It covers various scientific fields like biology, chemistry, physics, and computer science.
- The aim is to gather and analyze evidence supporting legal proceedings (criminal or civil).
- Forensic scientists use specialist tools to determine the physical, chemical, and biological makeup of evidence.
Types of Forensic Science
- Forensic Biology: Examines biological evidence (DNA, blood, hair).
- Forensic Chemistry: Analyzes chemical substances (drugs, poisons, explosives).
- Forensic Toxicology: Identifies and measures toxins/poisons in biological samples.
- Forensic Pathology: Investigates the cause and manner of death.
- Forensic Odontology: Uses dental records for identification and event reconstruction.
- Forensic Anthropology: Applies skeletal analysis for identification.
- Forensic Engineering: Examines structural failures.
- Forensic Document Examination: Analyzes documents for forgery/alterations.
- Forensic Computer Science: Investigates digital evidence (files, emails, social media).
Forensic Evidence Analysis Techniques
- DNA profiling: Identifies individuals based on unique DNA patterns.
- Bloodstain pattern analysis: Determines bloodstain origin, direction, and injury type.
- Firearm analysis: Examines firearms/ammunition to find projectile source.
- Trace evidence analysis: Examines small evidence like fibers, glass, paint.
- Chemical analysis: Uses techniques like spectroscopy & chromatography for substance identification/quantification.
- Microscopy: Examines trace evidence at high magnification for details.
- Ballistics: Investigates projectile trajectory and characteristics.
- Fingerprinting: Identifies individuals based on unique ridge patterns.
- Photography: Documents crime scenes and evidence with high fidelity.
- Video analysis: Examines video recordings of events.
- Digital forensics: Collects & analyzes data from digital devices (crime scene).
Key Roles in Forensic Science
- Forensic Scientists: Conduct experiments, analyze evidence, and report findings.
- Crime Scene Investigators (CSIs): Document & collect evidence at scenes, preserving integrity.
- Expert Witnesses: Testify and interpret scientific evidence in court.
- Police Officers: Facilitate communication between forensic teams and investigations.
Importance of Forensic Science
- Solving crimes: Identifies perpetrators and reconstructs events.
- Ensuring justice: Provides accurate and unbiased evidence in legal proceedings.
- Supporting investigations: Aids in understanding crime details.
- Protecting the innocent: Exonerates individuals and supports legal defense.
- Understanding criminal behavior: Provides insights into criminal activity.
- Improving safety: Offers methods to prevent future incidents.
- Documenting past events: Preserves historical records and studies.
Challenges in Forensic Science
- Advancing scientific methods: Keeping pace with advancements for better accuracy/efficiency.
- Interpretation of data: Ensuring clear and unbiased interpretations.
- Handling sensitive evidence: Safe and appropriate handling of biological/chemical samples.
- Maintaining integrity of chain of custody: Ensuring proper evidence handling throughout the process.
- Time constraints: Forensic analysis often faces pressure due to court deadlines.
- Cost effectiveness: Balancing thorough analysis and budgetary limitations.
