National Protective Security Officer Training Program Practice Test

The primary role of Protective Security Officers (PSOs) regarding crime scene protection is to ensure that the scene is secure until law enforcement arrives. This responsibility involves isolating the area, preventing unauthorized access, and safeguarding any evidence that may be present. By securing the crime scene, PSOs help maintain the integrity of the site, which is essential for any subsequent investigation by law enforcement. This protection is crucial in preventing tampering or alteration of evidence, which could hinder an investigation and prosecution.

The other roles mentioned, like actively investigating the scene, collecting evidence, or documenting personal observations, fall outside the PSO's primary responsibilities when it comes to crime scenes. Investigation of the scene and evidence collection are tasks designated specifically for law enforcement professionals who possess the necessary training and legal authority to conduct such activities. Likewise, while recording observations can be useful, it is typically done in a formal capacity by law enforcement rather than by PSOs at a crime scene.
