During an investigation, what is a vital rule regarding the release of personnel?

The vital rule regarding the release of personnel during an investigation is to ensure that they are released to the appropriate authority. This is crucial because it maintains the integrity of the investigation and ensures that individuals are not released without proper authorization, which could compromise evidence or safety. Releasing personnel to the appropriate authority also ensures that the investigation can continue smoothly and that any necessary follow-up actions can be taken.

Appropriate authority may vary depending on the circumstances, but it generally involves coordinating with the proper legal or investigative entities that have jurisdiction over the situation. This rule upholds the chain of command and legal standards, contributing to the overall accountability of the security forces during an investigation.
