What is the role of forensic science in the criminal justice system?

The role of forensic science in the criminal justice system is primarily focused on analyzing physical evidence. This involves the application of scientific methods and techniques to collect, preserve, and examine physical evidence from crime scenes. Forensic scientists utilize various disciplines such as biology, chemistry, and physics to assess evidence, which can include anything from fingerprints and blood samples to firearms and toxic substances. The results of these analyses are crucial for establishing facts in a case, providing law enforcement and the judiciary with objective data that can support or refute claims made during investigations or trials.

In contrast, although witness testimony can be important, it is not the primary focus of forensic science, and witness analysis falls under the purview of legal professionals rather than forensic scientists. Conducting legal investigations is also not the role of forensic science; instead, forensic professionals support these investigations with scientific findings. Lastly, the enforcement of law regulations is the responsibility of law enforcement agencies and does not directly involve forensic scientific analysis, which aims to provide impartial evidence for judicial processes.
