Which factor is NOT used to determine a predominant aggressor?

The correct answer highlights that the duration of the conflict is not a factor considered when identifying a predominant aggressor in situations involving domestic violence. The predominant aggressor analysis focuses on understanding the dynamics of the situation, including the history of violence, behaviors of those involved, and external observations.

Historical acts of domestic violence provide important context that helps law enforcement identify patterns and assess the situation accurately, suggesting a history that may influence the current event. Statements made by non-involved witnesses offer an external perspective that can materially affect the understanding of the incident and provide clarity on the behaviors of those involved. The extent of fear experienced by the parties involved indicates the psychological impact of the conflict and can be pivotal in sorting out who may be the actual aggressor, especially in a situation where both parties may present as victims.

In contrast, the duration of the conflict does not directly determine who the predominant aggressor is. While it might provide some context or background to the situation, it does not speak to the immediate behaviors or historical patterns that are critical in making that determination. Therefore, it is not a relevant factor in the assessment of aggressor dynamics in domestic violence contexts.
