During surveillance, can you assume a suspect will exit a building through the same door they entered?

Assuming a suspect will exit a building through the same door they entered is not a reliable tactic during surveillance, as individuals often choose to exit through different doors based on several factors, including changes in their surroundings, the situation, and their intended direction after leaving.

A suspect may have multiple options for exiting a building, and their choice of exit can be influenced by the need to avoid detection, respond to a perceived threat, or access a quicker route. For instance, if they notice that they are being followed or observed, they might opt for a less conspicuous exit to evade potential surveillance.

Moreover, the layout of the building may provide various exit points that are equally valid for use, regardless of the entrance. They might also choose to blend into a crowd or enter an adjacent building to throw off any pursuers. Consequently, maintaining flexibility and watching multiple exits is crucial during surveillance to effectively track a suspect's movements.
