What is forensic science?
- Jim Fraser
Forensic science is described as the investigation, explanation, and evaluation of events of legal relevance including the identity, origin, and life history of humans, materials, substances, and artefacts. Scientific methodologies are used to describe, infer, and reconstruct events from fragmentary physical evidence and other relevant information. Based on this analysis, forensic scientists answer the central questions in a criminal investigation: who, what, where, when, how, and why? But whilst the science behind forensic analysis is universal, the law is not, and varies widely from country to country. What may be inadmissible evidence in one legal system may secure a conviction in another.
