What are the two reasons for securing the crime scene?

1. Use crime scene tape; prevent public access

2. Protect from contamination; prevent removal of evidence

3. Lock the doors; call your supervisor

4. Sketch the crime scene; call photo lab

The correct answer is: Protect from contamination; prevent removal of evidence

The rationale for selecting the option regarding protecting from contamination and preventing the removal of evidence is rooted in the fundamental responsibilities of law enforcement when managing a crime scene. Securing a crime scene is critical to preserving the integrity of the investigation, and contamination can undermine the reliability of evidence collected at the scene. Contamination may occur from untrained personnel trampling through the area or introducing foreign materials that could alter or destroy the evidence. Additionally, safeguarding against the removal of evidence is crucial. Evidence collected from a crime scene is often vital for establishing facts, linking suspects to the crime, and supporting the case in court. If evidence is removed or tampered with before it can be documented or collected properly, it could lead to gaps in the investigation, potential loss of convictions in court, or wrongful accusations. The other options do not fully encapsulate the broader objectives of crime scene security, as they focus on specific actions or aspects that do not encompass the primary aims of preventing contamination and eliminating the risk of evidence being compromised or lost.
