The focus when addressing a gunshot or knife wound is to ensure that any evidence related to the incident is preserved and not disturbed. Holes in clothing can directly indicate the location and type of wound sustained by the individual. Disturbing these holes may compromise important forensic evidence that could be critical for investigations.

In this context, bloodstains, suicide notes, and tire marks, while potentially relevant to the scene, do not directly relate to the immediate assessment of the wound itself. Therefore, careful handling of the clothing is essential to maintain the integrity of evidence as it pertains directly to the wound assessment and the incident dynamics.
