What type of individuals might have a caution indicator added?

A caution indicator is typically added to individuals who pose a potential risk to themselves or others, particularly in specific situations such as being armed, suicidal, or having escaped custody. This serves as a precautionary measure for law enforcement and other agencies to ensure proper handling of encounters with these individuals. The use of caution indicators is critical in maintaining safety during any interactions, as they alert officers to the possible behaviors or situations involving these individuals.

The options that discuss individuals labeled as missing on their birthday or those with prior convictions may not trigger a caution indicator unless specific risks are present. Additionally, individuals with no criminal background generally wouldn't be flagged unless there are other serious concerns warranting such an alert. Therefore, the correct answer highlights the real focus of these caution indicators in ensuring public safety and officer awareness during potential encounters.
