What is the chain of custody primarily used for in forensic science?

Demonstrating evidence was handled properly
Collecting fingerprints at a crime scene
Evaluating the credibility of witnesses
Ensuring proper arrest procedures were followed

The correct answer is: Demonstrating evidence was handled properly

The chain of custody is crucial in forensic science as it establishes a documented history of the evidence from the moment it is collected until it is presented in court. This process involves tracking each person who handles the evidence, the circumstances under which it was transferred, and the methods used for securing it throughout the entire investigation. By demonstrating that the evidence has been handled properly, the chain of custody helps to maintain its integrity and reliability, ensuring that it has not been tampered with or contaminated, which is essential for its admissibility in legal proceedings. Furthermore, this thorough documentation is fundamental in reassuring the court and jurors that the evidence presented is authentic and trustworthy. This makes the role of the chain of custody indispensable in upholding the principles of justice and the integrity of the forensic process.
