Which of the following lists the deadly force determining factors?

• A. Intent and Opportunity only
• B. Means and Ability only
• C. Opportunity and Intent only
• D. Intent, Means, Ability, Opportunity

Answer: (D)

Four factors are used to determine whether deadly force is justified: Intent, Means, Ability, and Opportunity. Intent is the subject’s purpose or threat to cause death or serious bodily harm. Means is the instrument that could cause that harm, such as a weapon or other capable tool. Ability means the person actually has the capability to use the instrument effectively—they can reach, operate it, and cause harm now. Opportunity is the chance to use the force without delay, meaning they are in a position to carry out the threat imminently.

When all four factors are present, the belief that deadly force is necessary is grounded in observable circumstances and supports a justified decision. If any factor is missing, the justification becomes weaker because the person might have a weapon but no imminent plan to use it, or they may have the means but lack the ability or opportunity to apply it.

In practice, evaluations are based on the totality of circumstances, but the strongest justification for deadly force involves Intent, Means, Ability, and Opportunity together.
