When must RELD be included in the Locate message?

Including the Reporting Entity Location Data (RELD) in the Locate message is essential when the agency advises the locating agency not to detain. This is a critical piece of information that clarifies the status and intentions regarding the subject in question. By providing RELD, the locating agency can understand the context of the situation, especially if there are directives in place that might affect how they engage with the individual.

This inclusion helps prevent any potential issues that could arise from misunderstandings or actions taken by the contacting agency that may not align with the original agency's instructions. By ensuring that RELD is part of the communication, it enhances situational awareness and helps maintain the safety of all parties involved.

In contrast, the other situations do not necessitate the inclusion of RELD in the same way. For instance, when a missing person has been found, informing the locating agency about the status may be sufficient without needing to provide location data. Similarly, situations concerning a suspect posing a danger or when a case is still under investigation could have differing protocols that do not specifically require RELD. Thus, the requirement for including RELD is specifically tied to situations where agency instructions about detainment are present.
