Loitering, unusual movements, or attempting to conceal one's identity are commonly recognized indicators of suspicious behavior because they deviate from normal patterns of activity, especially in environments where people typically engage in purposeful actions. When individuals linger without a clear reason, particularly in a location that does not facilitate such behavior, it raises questions about their intentions. Unusual movements, such as frequently looking over one's shoulder or moving in a hesitant manner, can indicate that a person is trying to avoid detection or is uncertain about their actions, which can be a red flag in a security context. Additionally, attempts to obscure one's identity, whether through disguises or other means, often suggest that a person may be trying to engage in illegal or harmful activities.

The other options do not necessarily signify suspicious behavior. Smiling and waving at pedestrians is generally considered friendly and non-threatening. Carrying a visible backpack in a crowded area does not imply malicious intent, especially since many individuals carry belongings for perfectly harmless reasons. Using a mobile phone frequently could be a normal activity for many people and does not inherently indicate suspicious behavior.
