What does the "chain of custody" refer to?

The concept of "chain of custody" refers specifically to the process of maintaining and documenting the handling of evidence from the time it is collected until it is presented in court. This process is critical to ensure that the evidence remains intact, unaltered, and credible. Each individual who handles the evidence is recorded, including details about who collected it, who analyzed it, and how it was stored at every step. This meticulous documentation serves to establish the evidence's integrity, which is essential for its admissibility in court. Any breaks in the chain of custody can lead to questions about the validity of the evidence and could potentially compromise a case.

The options related to the order of arresting suspects, how evidence is disposed of, and the timeline of an investigation, while relevant to law enforcement procedures, do not specifically address the critical aspect of tracking and safeguarding the evidence itself, which is the essence of the chain of custody.
