What should a surveillant do if they believe they have been discovered?

If a surveillant believes they have been discovered, the appropriate action is to discontinue participation in the operation. This decision is grounded in the principles of operational security and personal safety. Continuing the surveillance in a full manner could not only place the surveillant at risk but also jeopardize the entire operation. Recognizing that being discovered may indicate potential danger or lack of cover, the best course of action is to withdraw to ensure safety and to reassess the situation.

Moreover, discontinuing the operation allows for the regrouping and evaluation of further actions. This pause is essential to avoid escalating the situation, which could lead to confrontation or compromise the integrity of the investigation. It also provides an opportunity to plan a more strategic approach if surveillance needs to be resumed, ensuring that future efforts are conducted more effectively and safely.

Other actions, such as alerting law enforcement or changing locations frequently, may not address the immediate need for safety and could lead to more complications if the situation escalates. Therefore, stopping the surveillance operation is the most prudent decision in such circumstances.
