What is the purpose of a security guard randomly selecting patrol and changing times?

The purpose of a security guard randomly selecting patrol and changing times is fundamentally aimed at preventing potential offenders from monitoring the guard's movements and establishing patterns. When patrols are timed unpredictably, it becomes significantly more challenging for potential intruders or individuals with harmful intentions to devise a strategy or gauge when security weaknesses may exist. This unpredictability enhances the overall security of the area by creating an environment of uncertainty for any would-be offenders, thereby deterring them from attempting to exploit vulnerabilities.

While there are other elements to consider—such as ensuring coverage of areas and managing guard behavior—these do not encapsulate the primary intention of randomizing patrols as effectively as it relates to thwarting the ability of offenders to observe and plan based on expected patterns of behavior.
