Police brutality laws give you two main ways to hold an officer accountable for using excessive force: a civil lawsuit under 42 U.S.C. § 1983 for violating your constitutional rights, and federal criminal prosecution under 18 U.S.C. §§ 241 and 242. A few states have added their own civil rights statutes that make these cases easier to win, and the Fourth Amendment supplies the core standard courts use to decide whether force crossed the line.
What Counts as Excessive Force
The Fourth Amendment prohibits unreasonable seizures, and courts treat any physical force during an arrest or stop as a seizure of the person.1Congress.gov. U.S. Constitution – Fourth Amendment The Supreme Court’s 1989 decision in Graham v. Connor set the controlling test: force must be judged by whether a reasonable officer facing the same facts would have acted the same way. The analysis is objective. An officer’s personal intentions do not matter.2Justia. Graham v. Connor, 490 U.S. 386 (1989) Courts weigh the severity of the crime at issue, whether the person posed an immediate safety threat, and whether the person was actively resisting or trying to flee.
Deadly force gets a stricter rule. Under Tennessee v. Garner, officers cannot shoot a fleeing suspect unless they have probable cause to believe the suspect poses a significant threat of death or serious physical injury to the officer or others. Where feasible, the officer must give a warning first.3Justia. Tennessee v. Garner, 471 U.S. 1 (1985) Many excessive force cases are won or lost in the gap between what an officer claims they feared and what the evidence actually shows.
Which amendment applies depends on your status during the encounter. For a free person being arrested or stopped, it’s the Fourth Amendment. For someone already convicted and serving a sentence, the Eighth Amendment’s ban on cruel and unusual punishment governs.4Congress.gov. U.S. Constitution – Eighth Amendment For someone held before trial, the Fourteenth Amendment’s Due Process Clause applies, and courts ask whether the force amounted to punishment rather than a legitimate security measure.5Legal Information Institute.

Suing the Officer Under Section 1983
The primary tool for suing a police officer is 42 U.S.C. § 1983, which makes any government official personally liable for depriving someone of constitutional rights while acting in an official capacity.6Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights You have to prove two things: the officer acted “under color of law” (using their badge, uniform, or authority), and the officer’s conduct violated a specific constitutional right.
Damages fall into three categories. Compensatory damages cover medical bills, lost wages, emotional distress, and other measurable harms. Punitive damages are available against the individual officer when the conduct was motivated by malice or showed reckless indifference to your rights. Nominal damages, typically one dollar, apply when a violation occurred but caused no substantial financial loss. That last category still matters because it establishes the violation on the record.
A separate statute, 42 U.S.C. § 1988, lets courts award reasonable attorney fees to the prevailing plaintiff.7Office of the Law Revision Counsel. 42 U.S.C. 1988 – Proceedings in Vindication of Civil Rights That fee-shifting provision is what makes most of these cases financially viable, since the cost of litigating against a government defendant would otherwise price most victims out of court.
The Qualified Immunity Problem
Before a § 1983 case reaches a jury, it almost always runs into qualified immunity. The doctrine shields government officials from personal liability unless they violated “clearly established” law. Courts apply a two-part test. First, did the officer’s conduct violate a constitutional right? Second, was that right so clearly established that any reasonable officer would have known the conduct was unlawful?
Most cases die on the second prong. In practice, “clearly established” means you need to point to an earlier court decision with nearly identical facts holding that the same type of conduct was unconstitutional. If no prior case is a close enough factual match, the officer gets immunity, even when the constitutional violation seems obvious. The Supreme Court’s 2009 decision in Pearson v. Callahan let lower courts skip the first prong and dismiss on the second alone, which means courts can avoid ever ruling on whether a constitutional violation actually occurred.8Justia. Pearson v. Callahan, 555 U.S. 223 (2009) That creates a loop: the law never gets “clearly established” if courts keep skipping the constitutional question.
Qualified immunity applies only to individual officers. It does not protect the municipality or police department itself. And it does not apply in criminal cases.
Suing the City or County
You can sue a municipality under § 1983, but not just because it employs the officer who hurt you. Under Monell v. Department of Social Services, a city or county is liable only when the constitutional violation resulted from an official policy, a widespread custom or practice, or a decision by a final policymaker.9Justia. Monell v. Department of Social Services, 436 U.S. 658 (1978) An officer going rogue on their own initiative does not make the city liable.
What does create municipal liability is a pattern of similar violations that leadership knew about and ignored, a training program so deficient it amounted to deliberate indifference toward residents’ rights, or an explicit department policy authorizing the unconstitutional conduct. These cases are harder to win than suits against individual officers, but they often produce larger settlements because the municipality has deeper pockets. One limitation: punitive damages cannot be assessed against a municipality. The reasoning is that punishing the city ultimately punishes taxpayers who had nothing to do with the misconduct.
Federal Criminal Charges
When police misconduct rises to the level of a crime, two federal statutes come into play. The more commonly charged is 18 U.S.C. § 242, which makes it a federal offense for anyone acting under color of law to willfully deprive a person of their constitutional rights. The base penalty is up to one year in prison. If the violation involves bodily injury, the maximum jumps to ten years. If the conduct results in death, or involves kidnapping or sexual assault, the officer faces potential life imprisonment or the death penalty.10Office of the Law Revision Counsel. 18 U.S. Code 242 – Deprivation of Rights Under Color of Law
The word “willfully” is doing heavy lifting. Federal prosecutors must prove the officer had the specific intent to violate a protected right, a significantly higher bar than the negligence or objective-reasonableness standards used in civil cases. That is why federal criminal convictions of police officers remain relatively rare even when the underlying conduct was clearly excessive.
When two or more officers coordinate to violate someone’s rights, 18 U.S.C. § 241 provides a conspiracy charge. The standard penalty is up to ten years in prison, with the same escalation to life imprisonment or death when the acts result in killing, kidnapping, or sexual assault.11Office of the Law Revision Counsel. 18 U.S.C. 241 – Conspiracy Against Rights Section 241 can reach officers coordinating a cover-up after a use-of-force incident or agreeing ahead of time to use unlawful force during a planned operation.
State Laws That Remove Qualified Immunity
Frustrated by qualified immunity in federal court, a handful of states have enacted their own civil rights statutes that let victims sue officers in state court with no qualified immunity defense available. As of 2025, only three states have passed laws explicitly eliminating qualified immunity for law enforcement, though some individual cities have adopted local ordinances doing the same. These state laws typically create a separate cause of action under the state constitution’s bill of rights, provide for attorney fees, and in some cases impose personal liability caps on officers found to have acted in bad faith.
The effect is real but limited in geography. In states without these laws, qualified immunity remains the dominant barrier to civil rights litigation, and multiple federal reform proposals have not become law. Whether you can effectively sue an officer depends heavily on where you live.
Deadlines and How to Report Misconduct
Section 1983 has no built-in statute of limitations. Courts borrow the deadline from the state where the incident occurred, using whatever time limit that state sets for personal injury lawsuits.12Justia. Wilson v. Garcia, 471 U.S. 261 (1985) Depending on the state, that window runs from one to six years, with two or three years being most common. Missing the deadline almost always kills the case entirely, regardless of how strong the underlying claim. The clock generally starts on the date of the incident, though exceptions exist when injuries were not immediately discoverable or when the misconduct is ongoing.
To trigger a criminal investigation, you can report the incident to the FBI, which handles investigative work for potential prosecution under 18 U.S.C. §§ 241 and 242.13Department of Justice. Contact the Civil Rights Division The DOJ’s Civil Rights Division also takes reports through its online portal. Filing an internal affairs complaint with the officer’s department is not a legal prerequisite to a federal civil rights lawsuit, but documenting the incident through every available channel strengthens any eventual claim.
Preserving evidence immediately after an incident makes a practical difference. If body-worn cameras were active, that footage is often the single most important piece of evidence in a use-of-force case. Access varies widely. No uniform national standard governs public disclosure of body camera video, and individual departments set their own retention and release policies. Request the footage in writing as soon as possible, and follow up with a formal public records request under your state’s open records law. That creates a documented trail that makes it harder for the recording to quietly disappear.
