When an officer is instructed to "Stand by", what is expected?

When an officer is instructed to "Stand by," the primary expectation is that they should prepare for further instructions. This phrase indicates that the officer needs to be in a state of readiness, allowing them to promptly respond to whatever commands or information may come next. It emphasizes the importance of being alert and poised to act as needed, rather than taking independent action or assuming a different role or assignment. The directive suggests that the situation may change or escalate, so maintaining readiness is crucial for effective law enforcement operations.
