In the example of Stalking, why was Andrea's brother's behavior concerning?

The concern regarding Andrea's brother's behavior is rooted in the nature of stalking itself, which is characterized by a pattern of repeated and targeted actions directed towards an individual. In this scenario, the repeated nature of the actions indicates an ongoing obsession or harassment that directly impacts the victim's sense of safety and well-being. Stalking behavior often includes not just one instance but a series of actions that create a credible threat or significant emotional distress for the person being followed.

The focus on "repeated and targeted actions" highlights the severity and intent behind the behavior, as opposed to just surveillance or presence which may not carry the same implications of threat. This differentiation is vital in understanding why certain behaviors can escalate to the level of stalking, and it's crucial in law enforcement and legal contexts to identify such patterns for appropriate interventions.
