How often should official requests for broadcast look-outs be made during serious incidents?

The correct choice of every 15 minutes for official requests for broadcast look-outs during serious incidents is established to ensure a balance between timely updates and operational efficiency. Frequent broadcasts help keep responding units informed about critical developments and suspects' descriptions, which is essential for a swift and coordinated response. However, intervals that are too short, such as every 5 or 10 minutes, could lead to information overload, causing confusion and potentially compromising communication effectiveness. Conversely, a longer interval, like every 20 minutes, may not provide adequate updates in fast-moving situations where circumstances can change rapidly. Therefore, the 15-minute interval is designed to optimize situational awareness while preventing unnecessary disruptions in radio communication.
