When is it necessary to initiate an 'all hands' call?

An 'all hands' call is a procedure used by law enforcement agencies to mobilize all available personnel and resources in response to a significant incident or emergency situation. This call is warranted specifically when there is a need for maximum resources to effectively manage the situation at hand.

In scenarios such as major public disturbances, significant criminal activity, or other high-impact events, a rapid and coordinated response is essential for ensuring public safety and maintaining order. Initiating an 'all hands' call facilitates a prompt assembly of officers and support staff who can provide the necessary manpower and expertise to handle the situation efficiently.

The other options do not warrant such a mobilization of resources. Routine patrol situations and low traffic hours typically do not require the extensive manpower invoked by an 'all hands' call, as they can be managed by the regular patrol officers on duty. Similarly, minor disturbances can often be resolved by a single officer or a small team without the need for a full-scale response. Therefore, option C is appropriate as it aligns with the need for maximum resources in critical situations.
