Touching or moving items at the scene can significantly compromise evidence preservation. When an evidence scene is disturbed, the physical integrity of potential evidence can be altered or destroyed. This includes not only the items themselves but also the context in which they existed—important details that could provide insights into the incident might be lost. Handling items incorrectly can lead to contamination, misplacement, or loss of critical evidence that could shape the investigation's outcome.

On the other hand, actions such as documenting the scene thoroughly, taking photographs of the incident, and conducting witness interviews on site actually help in preserving evidence and maintaining the integrity of the investigative process. These actions provide necessary documentation and context that assist law enforcement and investigators in understanding the details of the incident without altering what has been found at the scene.
