When planning to follow someone, what is one of the recommended strategies?

Knowing in advance where the subject is going is essential for effective surveillance. This strategy allows the investigator to plan the route, anticipate the subject's actions, and establish a better position to maintain observation without being detected. By having this information, the investigator can choose the best vantage points and avoid situations where they might lose the subject.

Revealing intentions to the subject would compromise the investigation, following too closely could raise suspicion and lead to the subject becoming aware of being followed, and using a drone for surveillance, while potentially useful, may not always be legally or practically feasible depending on the situation and regulations in place. Being prepared and informed about the subject's movements enhances the chances of success in obtaining necessary information without alerting the subject.
