Should you always work with original evidence in forensic investigations?

In forensic investigations, it is critical to preserve the integrity of the original evidence. This means that investigators should avoid working directly with the original data whenever possible. Instead, they should create copies or images of the data to work with during the analysis. By using copies, forensic analysts can ensure that the original evidence remains untouched, thus maintaining its integrity and admissibility in court.

Working with original evidence could lead to accidental alterations or damage, which could compromise the investigation and results. This practice follows the principle of "digital forensics" where maintaining a chain of custody and the integrity of original evidence is paramount. Therefore, the principle established by using copies supports a more accurate, reliable, and legitimate investigation process while safeguarding the original materials.
