Use-of-Force Law and the Reasonable-Person Standard

Use-of-Force Law and the Reasonable-Person Standard

Every time a security officer or law enforcement candidate touches another person, or even threatens to do so, the law is watching. Understanding the legal rules that govern use of force is not optional—it is the foundation of lawful practice and personal protection from criminal charges and civil liability.

The Reasonable-Person Standard

Courts measure whether force was justified by asking: What would a reasonable person in the same situation, with the same information, have done? This standard is objective, not based on what the individual officer felt. Fear alone is not enough to justify force; the fear must be one that a reasonable, trained person would share given the observable facts at that moment.

The U.S. Supreme Court case Graham v. Connor (1989) established that claims of excessive force by law enforcement officers are evaluated under the Fourth Amendment's objective reasonableness standard. Key factors the Court identified include: the severity of the crime or threat, whether the subject poses an immediate threat to the safety of officers or others, and whether the subject is actively resisting or attempting to evade. Although Graham addressed sworn officers, courts and licensing boards apply the same reasonableness logic when evaluating the conduct of security professionals.

Security Officer Authority vs. Sworn Officer Authority

This distinction is critical. A sworn peace officer has state-granted arrest powers, can carry a firearm under their commission, and operates under an extensive legal framework. A licensed security guard has far more limited authority—generally limited to the property they protect and to citizen's arrest powers as defined by state law. Security officers may not claim police powers. Exceeding that authority exposes the officer, their employer, and their client to serious legal liability. When in doubt, call law enforcement and document everything.

The Use-of-Force Continuum

Most states and agencies use a use-of-force continuum to guide decision-making. While exact models vary by jurisdiction, the general principle is the same: the level of force used must be proportional to the level of resistance or threat encountered. A common framework moves through levels such as:

1. Officer presence – the visible presence of a uniformed officer or guard, which alone may deter non-compliance.

2. Verbal commands – clear, calm instructions directing the subject's behavior.

3. Soft empty-hand control – guiding, escort holds, or stabilization techniques that minimize injury risk.

4. Hard empty-hand control – defensive strikes or takedowns used when lesser means have failed.

5. Intermediate weapons – tools such as chemical agents or impact devices, where authorized and trained.

6. Deadly force – force likely to cause death or serious bodily injury, used only when there is an imminent threat of death or serious bodily injury to the officer or another person.

Escalation and de-escalation both matter. An officer must be prepared to step down the continuum the moment the threat level decreases. Continuing to apply a higher level of force after a threat has ended can transform a lawful act into an unlawful one.

Justifiable Use of Force Under State Law

Your state statute on justifiable use of force defines exactly when force is permitted. Common elements across most states include:

• The person using force must have a reasonable belief that force is necessary.
• The threat must be imminent—not past, not future, but happening now.
• The force used must be proportional to the threat faced.
• There must be no reasonable alternative available (duty to de-escalate or retreat may apply depending on the state and context).

Always study the exact language of your state's statute; your State Security Guard License exam will test your knowledge of your own state's law.

Documentation and Reporting

After any use-of-force incident, a written report is required. Reports must be factual, written as soon as possible after the event, and describe the observable behaviors that led to each force decision. Phrases such as "I felt threatened" must be supported by specific observations: "The subject raised a clenched fist and stepped toward me." Vague or incomplete reports are a legal liability.

Safety First

Before any physical intervention:

• Assess the scene for additional threats, weapons, or bystanders.
• Never enter a situation alone when backup is available.
• Once a subject is restrained, monitor for signs of medical distress—positional asphyxia is a recognized risk and must be taken seriously.
• If an injury occurs—to any party—obtain medical assistance immediately.

Force is always a last resort. De-escalation, distance, and communication protect everyone, including you.
