The elimination of all other viable alternatives before using deadly force is called what?

• A. Target acquisition
• B. Target identification
• C. Target isolation
• D. Preclusion

Answer: (D)

The main concept is that deadly force should be used only after every viable option has been eliminated. This idea—preclusion—means an officer must assess and exhaust alternatives like verbal commands, de-escalation, increasing distance or cover, and using less-lethal tools before resorting to lethal force. If there’s a feasible non-deadly option or a situation where harm can be avoided, those options must be pursued; deadly force is considered only when there is an imminent threat and no reasonable alternatives remain.

Other terms don’t fit because they describe different actions: locating who to engage (target acquisition) or confirming who the person is (target identification), or simply separating the person from others (target isolation). None of these capture the requirement to exhaust all viable alternatives before using deadly force.
