3.3 Use of Force Continuum, Objective Reasonableness & Liability

3.3 Use of Force Continuum, Objective Reasonableness & Liability

Quick Answer: Every application of physical force by private security must be objectively reasonable, proportional, and immediately necessary under the totality of circumstances. Under the Graham v. Connor standard, force is evaluated from the perspective of a reasonable officer on the scene rather than with 20/20 hindsight. Officers must de-escalate force as resistance subsides, immediately place restrained individuals into a recovery position to prevent fatal positional asphyxia, and uphold their affirmative duty to intercede against peer misconduct.

The application of force in private security is governed by constitutional principles, state statutes, common law torts, and professional administrative regulations. Understanding how to select the appropriate level of force on the Force Continuum, recognizing the medical hazards of physical restraint, and understanding the profound legal consequences of excessive force are essential competencies for every Pennsylvania security professional.

The Private Security Force Continuum

The Force Continuum is an operational decision-making model that guides an officer in escalating or de-escalating force proportionally in response to a subject's behavior.

Detailed Breakdown of Force Tiers

1. Level 1: Officer Presence: The visual presentation of authority through a clean, professional uniform, visible Act 235 credentials, erect posture, and attentive demeanor. Presence alone deters many criminal behaviors.
2. Level 2: Verbal Direction & De-escalation: Tactical communication, active listening, clear concise commands, and emotional de-escalation techniques designed to achieve voluntary compliance without physical contact.
3. Level 3: Soft Empty-Hand Control: Low-injury physical techniques used against passive resistance or mild non-compliance, including escort holds, guiding positions, joint manipulation, and nerve pressure point application.
4. Level 4: Hard Empty-Hand Control: Higher-energy physical tactics used against active resistance or physical assault, including open-palm strikes, defensive forearm blocks, kicks, and dynamic ground takedowns.
5. Level 5: Intermediate / Less-Lethal Weapons: Specialized defensive equipment used when empty-hand control is insufficient to overcome aggressive assault, including Oleoresin Capsicum (OC) chemical spray, expandable batons, and Conducted Electrical Weapons (CEWs / Tasers).
6. Level 6: Deadly Force: The highest tier of force, involving the discharge of a firearm, strikes to lethal anatomical areas (temple, trachea, spine), or edged weapons, authorized solely to prevent death or serious bodily injury.

Objective Reasonableness: The Graham v. Connor Standard

Graham v. Connor, 490 U.S. 386 (1989) holds that claims of excessive force by law enforcement during an arrest, investigatory stop, or other seizure are analyzed under the Fourth Amendment's "objective reasonableness" standard. It is a constitutional rule about government actors, and a private security officer is normally not one — so Graham does not directly govern a private guard's conduct. It matters anyway for two practical reasons: PA's justification statutes in 18 Pa.C.S. Chapter 5 already turn on what the actor reasonably believes, so the analysis runs on parallel tracks; and courts, juries, employers, and Act 235 instructors routinely borrow the Graham factors as the vocabulary for evaluating reasonableness in negligence and assault claims against guards. Learn the factors — and learn that the case is about police.

The Core Holdings of Graham v. Connor

• No 20/20 Hindsight: The reasonableness of a particular use of force must be judged from the perspective of a reasonable officer on the scene, rather than with the 20/20 vision of hindsight.
• Split-Second Decisions: The calculus of reasonableness must embody allowance for the fact that security personnel are often forced to make split-second judgments in circumstances that are tense, uncertain, and rapidly evolving.
• Totality of Circumstances: Reasonableness is not determined by an officer's subjective underlying intent or motivation (good faith or malice), but whether the officer's physical actions were objectively reasonable given the facts known at that moment.

Proportionality and Dynamic De-escalation

Use of force is not a one-way street. It is fluid and dynamic. An officer must escalate when subject resistance increases, but is legally and ethically mandated to de-escalate immediately as subject resistance subsides.

The Transition Trap: Once a combative subject is placed in handcuffs and ceases struggling, the justification for Level 4 (hard strikes) or Level 5 (baton/OC spray) instantly terminates. Delivering strikes to a handcuffed, subdued subject constitutes criminal assault under Pennsylvania law.

Positional Asphyxia, Excited Delirium & In-Custody Safety

Positional Asphyxia occurs when a subject's body position severely restricts their ability to breathe, leading to oxygen deprivation, cardiac arrest, and death. It is one of the leading causes of in-custody death and massive civil wrongful death liability in private security.

Contributing Risk Factors for Positional Asphyxia

• Prone Restraint: Forcing a subject face-down on the ground with chest or diaphragm compression.
• Officer Body Weight: Kneeling or sitting on a subject's upper back, shoulder blades, neck, or torso.
• Excited Delirium Syndrome: Extreme physiological distress characterized by hyperthermia, profuse sweating, extreme paranoia, unexpected physical strength, and respiratory exhaustion.
• Physiological Factors: Severe obesity, alcohol or drug intoxication (especially stimulants like cocaine, methamphetamine, or PCP), and cardiovascular disease.

  1. Restrain & Handcuff in Prone Position (Immediate Control Only)

  2. NEVER Apply Weight to Upper Back, Spine, or Neck

  3. IMMEDIATELY Transition to Recovery Position (Seated or Side-Lying)
                                  │
  4. Continuously Monitor Airway, Breathing, and Consciousness
                                  │
  5. Summon EMS Immediately if Subject Shows Respiratory Distress

Duty to Intercede & Mandatory Reporting

Under professional standards, Act 235 regulatory principles, and prevailing tort law, private security personnel have an affirmative legal and ethical duty to intercede when observing a colleague or fellow officer applying unauthorized, excessive, or unconstitutional force.

Key Responsibilities

1. Active Physical / Verbal Intervention: If a fellow officer applies unreasonable force (e.g., striking a handcuffed suspect), the observing officer must verbally command them to cease and physically intervene if safe and necessary.
2. Mandatory Reporting: The observing officer must document the incident truthfully in an official operational report and notify supervisory personnel and law enforcement.
3. Failure to Intervene Liability: Officers who stand by and permit unlawful violence can be charged criminally as accomplices / co-conspirators and named as joint tortfeasors in civil litigation.

Legal Consequences of Excessive Force

Applying force beyond what is objectively reasonable triggers three distinct layers of liability:

Comprehensive Force Decision Matrix

Scenario: Prone Restraint in a Commercial Lobby

Incident: A highly agitated and intoxicated individual assaults a retail store manager. Two security officers physically subdue the subject on the lobby floor, holding him in a prone (face-down) position while securing handcuffs. Once handcuffed, the subject continues to shout profanities and thrash his legs. One officer places his full knee weight across the subject's mid-back to keep him pinned face-down on the floor for 10 minutes while waiting for police.

Legal & Tactical Analysis:

• Handcuffing Justification: Grounding and handcuffing the assaultive subject was reasonable under Level 4 hard empty-hand control.
• Tactical Error & Extreme Liability: Maintaining prone restraint with direct body weight on the back for 10 minutes creates massive risk of positional asphyxia.
• Proper Protocol: Immediately after the handcuffs were ratcheted, the officers were required to roll the subject onto his side or sit him upright, continuously monitor his breathing, and remove all downward pressure from his torso.

Exam Tip: The Graham Reasonableness Metric

When evaluating scenario-based use-of-force questions on the examination:

1. Check the subject's current behavior tier at the exact moment force was delivered.
2. Verify if the officer used the minimum necessary force to overcome resistance.
3. Determine whether the officer de-escalated once compliance or restraint was achieved.
4. Remember that subjective good intentions never excuse an objectively unreasonable application of force.
