Pre- and post-supervision

The advantages and Nachaufsicht are tactical measures before and after a major police operation . It serves both internal police interests (control of events) and the public good by containing security disruptions and above all the control (overview) of what is happening.

Pre-supervision (sometimes also called pre-investigation) is about protecting the operations command (e.g. operations manager, police officer ) from surprises, be it in the presence of (potential) interferers or at the location of a focal point . He and his staff should find the emergency room as they expect after assessing the situation at the start of the mission.

In closed operations , a separate section is usually responsible for pre- and post-supervision .
