According to the passage, which of the following affirmatives can be inferred from the text?

Criminal forensics, also known as forensic science, is a field that applies scientific methods and technical knowledge to the investigation of crimes. Forensic experts analyze physical evidence collected from crime scenes, such as fingerprints, DNA, weapons, documents, and digital data. Their work aims to reconstruct events and provide reliable technical evidence to support the criminal justice system. They also play a vital role in criminal investigations because they apply scientific knowledge to examine evidence related to crimes.

Forensic professionals must act with objectivity, impartiality, and scientific rigor. Proper evidence handling, including documentation and preservation, is essential to maintain the integrity of the evidence. One of the most important responsibilities of a criminal expert is maintaining objectivity. Instead of focusing on proving guilt or innocence, the expert’s duty is to analyze evidence in an impartial and scientific manner. This ensures that the conclusions presented in forensic reports are reliable and can be used in court.

One of the most important principles in forensic work is the chain of custody, which ensures that all evidence is properly tracked from collection to final presentation in court.

Another key aspect of the criminal expert’s work is evidence preservation. Crime scenes must be carefully protected to avoid contamination or loss of material. The expert documents each step of the evidence handling process through the chain of custody, which records who collected the evidence, how it was stored, and when it was transferred.

By providing accurate and well-documented technical reports, criminal experts support the justice system and contribute to fair legal decisions.
