What method is NOT a common terrorist method of surveillance?

The choice involving breaking and entering to steal valuables does not align with common terrorist methods of surveillance, which primarily focus on gathering intelligence rather than committing theft. Terrorists typically conduct surveillance to assess potential targets, gather information about security measures, and plan their operations. This involves observing behaviors, routines, and environments without arousing suspicion.

The other methods, such as technical surveillance, stationary surveillance, and casual questioning, are all tactical approaches employed to track or understand a target's movements and habits in a discreet manner. Technical surveillance might include the use of electronic devices to monitor conversations or movements, while stationary surveillance involves remaining in one spot to watch a target. Casual questioning can gather information from individuals without revealing the intent of the inquiry, which fits within the typical objectives of surveillance in planning an attack.

By focusing on these strategies, terrorists can compile the necessary information to select their targets and execute their plans effectively, making breaking and entering to steal valuables an unlikely method within this context.
