Police Use Of Force Case Law
I. Legal Framework: Police Use of Force
A. General Principles
Police officers are authorized to use force to enforce the law, protect themselves, and protect the public.
However, use of force must be reasonable and proportionate under the circumstances.
The Fourth Amendment (U.S. Constitution) protects individuals against unreasonable searches and seizures, including excessive force.
Courts often balance law enforcement interests against individual rights.
B. Reasonableness Standard
The central legal test for police use of force is whether it was objectively reasonable from the perspective of a reasonable officer on the scene.
The totality of circumstances must be considered — including threat posed, severity of crime, resistance, etc.
II. Key Case Laws on Police Use of Force
1. Graham v. Connor (1989)
Jurisdiction: United States Supreme Court
Facts:
Graham, a diabetic, was stopped by police after a rapid exit from a store.
Officer Connor used force during the stop that Graham claimed was excessive.
Legal Issue:
What is the proper standard for evaluating claims of excessive force under the Fourth Amendment?
Holding:
The Supreme Court ruled that claims of excessive force are analyzed under the Fourth Amendment’s reasonableness standard, not a substantive due process standard.
The "reasonableness" must be judged from the perspective of a reasonable officer on the scene, without the benefit of hindsight.
Factors to consider include:
Severity of the crime
Whether the suspect posed an immediate threat
Whether the suspect was actively resisting arrest or attempting to flee
Importance:
Established the "objective reasonableness" test still used today.
Emphasized that use of force claims must be judged with the pressures and split-second decisions officers face.
2. Tennessee v. Garner (1985)
Jurisdiction: United States Supreme Court
Facts:
Police shot and killed an unarmed fleeing suspect trying to escape after suspected burglary.
The suspect was shot in the back as he climbed a fence.
Legal Issue:
Is it constitutional for police to use deadly force to prevent the escape of a fleeing suspect?
Holding:
The Court held that deadly force may not be used unless:
The officer has probable cause to believe the suspect poses a significant threat of death or serious physical injury to the officer or others.
Deadly force to stop a fleeing suspect is unconstitutional if the suspect does not pose such a threat.
Importance:
Limited use of deadly force to situations where the suspect is dangerous.
Affirmed the importance of balancing public safety with suspect’s right to life.
3. Scott v. Harris (2007)
Jurisdiction: United States Supreme Court
Facts:
Police used a high-speed pursuit technique (ramming suspect's car) that caused serious injury.
The suspect sued, claiming excessive force.
Legal Issue:
Is the use of potentially deadly force during a high-speed chase reasonable?
Holding:
The Court ruled the police action was reasonable, given the threat the suspect posed to public safety during the chase.
The Court noted the importance of context: risk to innocent bystanders justified the use of force.
Importance:
Reinforced that police use of force must be judged with consideration of public safety risks.
Showed courts may uphold force used to prevent greater harm.
4. County of Los Angeles v. Mendez (2017)
Jurisdiction: United States Court of Appeals, Ninth Circuit
Facts:
Officers entered a home forcibly, used a Taser on a non-violent suspect.
Mendez sued for excessive force.
Legal Issue:
Was the use of a Taser reasonable under the circumstances?
Holding:
The court found the use of force excessive because the suspect was non-violent and posed no immediate threat.
Emphasized that less intrusive means should be used when the threat level is low.
Importance:
Highlights importance of proportionality in use of force.
Officers must tailor their force to the threat level and compliance of the suspect.
5. Kingsley v. Hendrickson (2015)
Jurisdiction: United States Supreme Court
Facts:
Inmates alleged excessive force during detention.
Legal Issue:
What standard applies to claims of excessive force by pretrial detainees?
Holding:
The Court ruled that pretrial detainees need only show that force used was objectively unreasonable, not intentional or malicious.
This is a lower standard than for convicted prisoners.
Importance:
Extended the objective reasonableness standard to detainees.
Signaled courts' focus on protecting civil rights during police and detention use of force.
III. Summary of Legal Principles from Cases
| Case | Legal Principle | Application |
|---|---|---|
| Graham v. Connor | Objective reasonableness under 4th Amendment | Evaluates force based on officer’s perspective |
| Tennessee v. Garner | Deadly force only for significant threat | Limits police shooting fleeing suspects |
| Scott v. Harris | Context of public safety justifies force | High-speed chases and public risk |
| County of Los Angeles v. Mendez | Proportionality and necessity of force | Use minimal force for non-threats |
| Kingsley v. Hendrickson | Objective standard for pretrial detainees | Protects detainee rights |
IV. Conclusion
Police use of force law is built on the balance between law enforcement duties and individual constitutional rights. Courts focus on:
The reasonableness of the force,
The immediacy and severity of threat,
The context of the incident,
The suspect’s behavior (resisting, fleeing, etc.).
Each case clarifies how courts evaluate facts and apply the reasonableness test differently depending on circumstances.
