11.2 PA Statutory Force Authority

11.2 PA Statutory Force Authority

Statutory Overview: While federal constitutional case law sets the minimum baseline for police use of force under the Fourth Amendment, state statutes prescribe the explicit statutory authority and restrictions for law enforcement officers operating within Pennsylvania. In the Commonwealth of Pennsylvania, police force authority is governed by Title 18 of the Pennsylvania Consolidated Statutes (18 Pa.C.S. § 508).

18 Pa.C.S. § 508: Use of Force in Law Enforcement

Chapter 5 of Title 18 outlines general principles of justification. Section 508 specifically governs Use of force in law enforcement, defining the legal bounds within which a peace officer may employ physical force or deadly force during arrests, detention, and self-defense.

Non-Deadly Force Authority (§ 508(a))

Under Pennsylvania law, a peace officer is justified in using physical force upon another person when the officer reasonably believes such force is necessary to:

1. Effectuate a lawful arrest;
2. Prevent the escape of an arrested individual from custody; or
3. Defend himself/herself or another person from bodily harm while making an arrest or preventing an escape.

The statutory standard requires that the officer maintain an honest and reasonable belief in the necessity of force. The degree of non-deadly force used must be proportional to the level of resistance encountered.

Statutory Restrictions on Deadly Force (§ 508(a)(1))

Pennsylvania law defines deadly force as force which, under the circumstances in which it is used, is readily capable of causing death or serious bodily injury (SBI). Serious bodily injury is further defined under 18 Pa.C.S. § 105 as bodily injury which creates a substantial risk of death or which causes serious, permanent disfigurement, or protracted loss or impairment of the function of any bodily member or organ.

Under 18 Pa.C.S. § 508(a)(1), an officer is justified in using deadly force ONLY when the officer reasonably believes that such force is necessary to prevent death or serious bodily injury to himself or another person, OR when all of the following conditions are met regarding a fleeing suspect:

1. The use of deadly force is necessary to prevent the arrest from being defeated by resistance or escape; AND
2. The person to be arrested has committed or attempted a forcible felony; OR
3. The person is attempting to escape and possesses a deadly weapon; OR
4. The person otherwise indicates that he will endanger human life unless arrested without delay.

Forcible Felonies Defined Under PA Law

A critical component of § 508(a)(1) is the statutory term forcible felony. Officers cannot use deadly force to stop escape simply because a crime is classified as a felony. The offense must meet the specific legal threshold of a forcible felony.

Under 18 Pa.C.S. § 108 and Pennsylvania judicial precedent, a forcible felony is defined as a felony involving the use or threat of physical force or violence against any individual.

Examples of PA Forcible Felonies:

• Criminal Homicide (Murder, Voluntary Manslaughter)
• Rape and Involuntary Deviate Sexual Intercourse (IDSI)
• Robbery (inflicting or threatening serious bodily injury)
• Kidnapping and Arson (where human life is endangered)
• Aggravated Assault (causing or attempting to cause SBI)
• Burglary of an Occupied Structure (adapted where violent threat exists)

Non-Forcible Felonies (Deadly Force Prohibited for Escape):

• Theft by Unlawful Taking (even high-value property theft)
• Forgery, Fraud, or Embezzlement
• Receiving Stolen Property
• Commercial Burglary of an Unoccupied Warehouse

Duty to Retreat & Police Officer Exemption (§ 508(a)(2))

In civilian self-defense law under 18 Pa.C.S. § 505, individuals may be subject to limitations regarding the duty to retreat before employing deadly force (subject to Castle Doctrine exceptions in one's home or vehicle).

However, 18 Pa.C.S. § 508(a)(2) explicitly establishes a legal exemption for police officers:

Police Exemption from Duty to Retreat: A peace officer making a lawful arrest is not bound to retreat or desist from efforts to make a lawful arrest because of resistance or threatened resistance by the person being arrested.

Legal Rationale

Police officers are societal agents charged with enforcing public order and taking dangerous offenders into custody. Requiring officers to retreat when encountering resistance would undermine lawful authority and compromise public safety. An officer may stand his ground, maintain control, and apply proportional, lawful force to overcome resistance.
