9.2 Legal Authorities and Reasonable Force

Key Takeaways

  • BPOC Chapter 28 ties force questions to Penal Code Chapter 9, especially justification, self-defense, defense of others, protection of property, and arrest or search.
  • Graham v. Connor is the core Fourth Amendment case for judging force under objective reasonableness.
  • Tennessee v. Garner is the core deadly-force case for fleeing-suspect limits.
  • Reasonableness depends on total circumstances, not a fixed force ladder.

Lawful Force Authority

TCOLE BPOC Chapter 28 starts use-of-force theory with legal authority. The exam commonly tests whether the officer can connect the level of force to a recognized law, not just to a feeling that the subject was difficult. The key Texas frame is Penal Code Chapter 9, including deadly force under PC 9.01(3), justification as a defense under PC 9.02, threats under PC 9.04, reckless injury to innocent third persons under PC 9.05, and arrest or search under PC 9.51.

Federal cases add the constitutional lens. Graham v. Connor uses Fourth Amendment objective reasonableness for claims that force during seizure was excessive. Tennessee v. Garner is the landmark limit on deadly force against a fleeing suspect. The exam does not ask you to brief cases like a lawyer, but it expects you to know that force is judged by facts known to a reasonable officer at the time.

AuthorityExam roleWhat to articulate
PC 9.21 and PC 9.22Public duty and necessityWhy lawful duty or necessity applied
PC 9.31 to PC 9.34Self-defense, deadly force, third person, life or healthThreat, immediacy, and degree of force needed
PC 9.41 to PC 9.44Property protection conceptsProperty interest and limits on force
PC 9.51 and PC 9.52Arrest, search, and escape preventionArrest authority, resistance, escape risk, and warnings when required
PC 9.05Innocent third person riskBystanders, background, crossfire, and foreseeable injury

The deciding factors from BPOC Chapter 28 are practical. Is the suspect peacefully submitting or resisting, armed or apparently armed, alone or part of a group, and suspected of what offense? Does the suspect have known violence history, what support is available, and what risk does the chosen force create for officers or bystanders? These facts drive reasonableness.

Scenario guidance: an officer tries to arrest a robbery suspect in a crowded convenience store parking lot. The suspect refuses commands, keeps one hand hidden, and starts moving toward bystanders. The best exam response identifies the offense severity, the hidden-hand risk, the crowd, available cover, backup, and communication efforts. It avoids saying use deadly force just because robbery is serious unless the facts show an immediate threat justifying it.

Articulation is part of the legal answer. TCOLE's required activities ask students to identify who, what, where, why, and how the facts apply to communications and reports. A report should not merely say the subject was aggressive. It should describe specific behavior such as clenched fists, closing distance, refusing to remove hands, reaching toward waistband, visible weapon, bystander location, and commands given.

Policy also matters. Chapter 28 says departmental policy should be at least as restrictive as law, and agencies may be stricter. On the exam, if one answer follows both law and agency policy while another relies on bare legal permission, choose the answer that respects both.

Exam trap: a fixed continuum answer is usually too rigid. TCOLE lists force options, but reasonableness depends on total circumstances. Another trap is ignoring PC 9.05. A force choice may be legally risky if it solves the suspect problem while creating an unreasonable danger to innocent third persons.
