Which approach should be taken for building checks?

The appropriate approach for building checks involves being attentive and aware of your surroundings, which aligns with listening for unusual sounds while driving past. This strategy emphasizes the importance of observation and auditory awareness, enabling an officer to detect any suspicious activity that might not be visible from a distance.

Being vigilant in this manner allows the officer to gather more information about the environment and potential threats, making it a proactive measure in maintaining security. This approach also supports the use of other surveillance techniques, such as observing behaviors and trying to identify irregularities that could indicate criminal activity.

In contrast, employing only directed patrols limits the scope of observation to predetermined areas, which may not be sufficient for comprehensive checks. Stealth methods can be useful but focusing solely on them can lead to missing out on observable cues in the environment. Performing checks in large groups may draw attention and could potentially be less effective for discreet surveillance, as the presence of many individuals might alter the behavior of anyone intending to commit a crime.
