Which method is NOT a terrorist method of surveillance?

The reason breaking and entering to steal valuables is not considered a method of surveillance is that it primarily involves committing a crime with the intent to steal rather than observing or gathering information about a target or environment. Surveillance, in the context of terrorism, refers to the monitoring and collection of information about people, locations, and systems to aid in planning an attack or furthering a terrorist agenda.

Methods of surveillance like technical surveillance, stationary surveillance, and casual questioning are all focused on gathering intelligence and assessing security measures, weaknesses, or behaviors related to potential targets. Technical surveillance might involve electronic means of monitoring, stationary surveillance entails observing from a fixed position, and casual questioning involves informal inquiries to gather information discreetly. Each of these approaches is strategic and aimed at collecting data that can inform planning and execution of terrorist activities. In contrast, breaking and entering is a direct criminal act against property rather than a means of obtaining information for planning purposes.
