Which of the following is a common crime scene problem?

Contamination is a significant concern at crime scenes because it can compromise the integrity of evidence collected. This issue arises when individuals who are not authorized to be at the scene come into contact with the physical evidence or when the evidence is inadvertently altered by environmental factors or the actions of first responders and investigators. Contamination can lead to the loss of critical information or misinterpretation of the scene, ultimately affecting the investigation and any subsequent legal proceedings. Proper containment and management of the crime scene are crucial to prevent contamination and to preserve the evidence in its original state. This highlights the importance of protocols and procedures that prevent unauthorized access and ensure that only trained personnel handle the evidence.
