Which action might suggest a person is observing or surveilling a location?

Staying in one place for an extended period can be a strong indicator that a person is observing or surveilling a location. Such behavior deviates from normal activity patterns, where individuals typically move through an area rather than linger. This prolonged presence can be seen as suspicious, particularly if the individual appears to be watching specific entrances, exits, or behaviors of others. In contexts where surveillance is a concern, individuals are often trained to look for signs of unusual behavior. Moving through an area, such as asking about restaurants, using transportation, or engaging in casual conversation, does not necessarily imply surveillance and may simply reflect typical activities of individuals going about their day. Thus, the act of remaining stationary and seemingly focused on a particular location is a clear indicator of observation or surveillance efforts.
