6.1 Use-of-Force Scenario Decision-Making

Key Takeaways

  • AUF Topic 9 trains low-frequency/high-risk force decisions through scenarios—not memorized scripts
  • Before using force, weigh threat immediacy, subject ability/opportunity/intent, available options, bystanders, and post orders
  • Unarmed guards facing armed suspects should usually evacuate, report, and avoid engagement unless policy and necessity require otherwise
  • Shoot/don't-shoot framing for unarmed posts means choosing observation, communication, cover, and reporting—not inventing lethal options you do not have
  • Real-time force-option decisions must stay objectively reasonable, the least intrusive option that works, and fully reportable after the fact

Appropriate Use of Force (AUF) Topic 9 focuses on scenario-based decision-making. On the BSIS Power to Arrest / Appropriate Use of Force exam and in field work, you will rarely face a textbook fight. You will face messy, fast, low-frequency/high-risk events: a subject reaching into a waistband, a crowd surrounding a detention, a vehicle accelerating toward a gate, or an armed person walking a mall corridor. Training uses simulations and tabletop scenarios because these events are rare but catastrophic when handled poorly.

This section teaches how California security guards should think under threat—especially unarmed guards, who make up most Guard Card holders. Your job is not to “win a duel.” Your job is to protect life and property within citizen authority, employer policy, and post orders, then document what happened.

Why low-frequency / high-risk training matters

Routine patrols build habits: greet, observe, report, lock doors. Force events break those habits. Stress narrows vision, speeds breathing, and pushes people toward the first option that feels familiar—often too much force, or freezing. Scenario practice builds a better default: slow the decision just enough to identify the threat, options, and legal limits.

Scenario typeFrequencyRisk if wrongGuard goal
Verbal dispute / trespassCommonMedium (false imprisonment, PR harm)De-escalate; document; avoid unnecessary detention
Physical assault on guard/patronUncommonHigh (injury, criminal/civil liability)Defend self/others with objectively reasonable force
Armed subject / robbery in progressRareExtremeEvacuate, report, observe from cover; avoid engagement
Active aggressor with weaponVery rareExtremeFollow active-shooter / post-order plan; notify law enforcement

Notice the pattern: as lethality rises, the correct unarmed-guard response usually moves away from contact and toward distance, cover, communication, and police notification.

Factors affecting response when you are threatened

When someone threatens you or others, several factors shape a reasonable response. Exam questions often hide these factors in short fact patterns.

1. Immediacy of the threat. Is harm happening now, about to happen, or only possible later? Imminent harm supports more immediate defensive action. A subject yelling insults from across a parking lot does not justify physical force.

2. Ability, opportunity, and intent (AOI). Ability means the person can cause harm (size, weapons, numbers). Opportunity means they can reach you or the victim now. Intent means words or actions show they mean to cause harm. Missing any of these usually means you should create distance, call for help, or use communication—not escalate to force.

3. Your tools and training. An unarmed guard with a radio and flashlight is not in the same position as an armed peace officer. Choosing an option you are not authorized or equipped to use is both dangerous and legally reckless.

4. Environment. Lighting, exits, crowd density, vehicles, glass, and confined spaces change options. In a crowded lobby, a takedown that might be reasonable in an empty hallway can injure bystanders and fail objective-reasonableness review.

5. Your role and post orders. Contract security protects a specific client site under specific rules. If post orders say “observe and report” for armed robbery, freelancing a citizen’s arrest of an armed robber is usually the wrong answer—even if you feel brave.

6. Availability of backup and law enforcement. If police are minutes away and you can maintain observation from cover, waiting is often the best “force option”—because the best option is frequently no force.

Factors to evaluate before using force

Before you apply force (including physical control, restraints if authorized, or defensive tactics), run a rapid checklist. You will not recite it aloud under stress, but training should make it automatic:

Pre-force questionWhy it matters
Is there a lawful purpose (self-defense, defense of others, authorized detention)?Force without lawful purpose is battery / false imprisonment risk
Have I tried or considered verbal commands / de-escalation?Least-intrusive option first when time allows
Is the force proportional to the threat?Objectively reasonable standard
Can I create time/distance/cover instead?Often safer and more defensible
What will bystanders / cameras see?Civil liability and BSIS / employer review
Can I articulate this in a report?If you cannot explain it, do not do it

Important: “Before using force” does not mean you must try every soft option while someone is actively stabbing a patron. Imminence compresses the checklist. The exam expects you to distinguish time-available situations from no-time situations.

Shoot / don’t-shoot framing for unarmed guards

Many AUF materials borrow “shoot / don’t-shoot” language from law-enforcement firearms training. For unarmed California security guards, reframe it:

  • “Shoot” equivalents you do not have: You typically have no firearm under a Guard Card alone. A separate BSIS Firearms Permit is required to carry a firearm on duty. Do not invent lethal options.
  • “Don’t-shoot” default that usually wins: Evacuate people from the danger zone, take cover/concealment, report to dispatch and 911 with suspect description/direction of travel, and do not engage armed suspects.
  • When limited force may still be required: If an unarmed subject is actively assaulting you or a helpless victim and escape is impossible, objectively reasonable defensive force to stop the attack may be justified—then disengage and summon police.

Real-time force-option decisions

Force options exist on a continuum, not a ladder you must climb in order when there is no time. Typical private-security options (subject to employer policy and training) include:

  1. Officer presence — visible uniform, calm stance, professional distance
  2. Verbalization — clear commands, tone control, warnings when feasible
  3. Empty-hand control — holds/escorts if trained and authorized
  4. Intermediate tools (only if trained, equipped, and permitted) — e.g., oleoresin capsicum, baton, handcuffs
  5. Deadly force — generally outside unarmed Guard Card practice; firearm only with proper permit and legal justification

Real-time decision rule for the exam: pick the lowest effective option that stops the imminent harm, then stop when the threat stops. Continuing force after compliance is a classic liability and ethics failure.

Scenario walkthrough (exam style)

Facts: You are an unarmed lobby guard. A person enters waving a knife, demanding the cash box. Two visitors freeze near the elevators. Post orders: observe and report for armed incidents; do not pursue armed suspects.

Sound decision path: Activate panic/duress if available → clear voice commands for visitors to move to the stairwell/exit away from the subject → take cover behind a structural barrier → radio/911 with description and location → keep eyes on from a safe position if possible → do not rush the knife → meet responding officers with a concise brief.

Unsound decision path: Charging the subject to “save the cash,” wrestling for the knife untrained, or locking yourself in with the subject to “contain” them without a plan.

After-action discipline

Every force or near-force event needs: medical check for injured parties, scene preservation as practical, supervisor notification, and a factual report (who/what/when/where/why force was needed, options considered, and when force stopped). Memory fades; write early.
