When you file a complaint against a police officer, the agency screens it, assigns it to an investigator if it clears intake, builds a factual record through interviews and evidence, and issues a formal finding on each allegation. Minor matters can wrap up in weeks; serious allegations often take a year or more. Only a small share of complaints end in a sustained finding and discipline, but filing still creates a paper record and leaves every other legal option — federal complaint, civil lawsuit, oversight board review — fully available to you.
How the Complaint Enters the System
Most complaints go directly to the officer’s agency, usually through its Internal Affairs division. You can file in person, by phone, by mail, or online. You don’t need a lawyer, and you don’t need the officer’s name or badge number, though any identifying details speed things up.
The complaint form will ask for the date, time, and location of the incident, a written account of what happened, and contact information for witnesses. Before you submit, pull together whatever evidence you have: photos, video or audio, medical records, receipts, anything that documents the encounter. Strong supporting material makes it harder for the investigation to stall on a credibility dispute.
Some cities and counties also run civilian oversight boards that take complaints independently of the police department. Their authority varies. Some can investigate on their own and issue binding recommendations; others only review what the department already did. If your area has one, filing with both the agency and the board puts your complaint on two tracks.
Once your complaint arrives, a supervisor or intake officer screens it. This preliminary review decides whether the agency has authority to act and whether the allegation, if true, would actually violate law or policy. Complaints that are plainly frivolous, too thin to act on, or outside the agency’s jurisdiction get filtered out here. For minor issues like rudeness, the complaint may go to the officer’s supervisor for informal resolution — a conversation with the officer, additional training, or mediation if both sides agree. That path still creates a record in the officer’s file.
Pay attention to deadlines. Timeframes vary by jurisdiction, and some places limit how far back an incident can be and still be investigated. File promptly.
The Formal Investigation
If the complaint moves forward, it gets assigned to a detective in Internal Affairs or a staff member of the civilian oversight body. The investigator’s job is to build a factual record and measure what happened against policy and law.
You should expect to be contacted for a formal, recorded interview where you walk through your account in detail. The investigator will also interview the officer and other witnesses, and will collect body-worn and dashboard camera footage, police reports, dispatch logs, and any other available evidence. Follow-up contacts are common, both to clarify inconsistencies and to fill gaps. Your cooperation matters. Investigations that stall often stall because the complainant stopped responding.
The Officer Has to Answer
One feature surprises most people: the officer under investigation is required to answer the investigator’s questions. That obligation traces to the Supreme Court’s 1967 decision in Garrity v. New Jersey, which held that public employees can be compelled to give statements as a condition of their employment, and that those compelled statements cannot be used against them in a criminal prosecution.1Justia US Supreme Court. Garrity v New Jersey, 385 US 493 (1967) An officer who refuses to answer the administrative investigator can be fired for insubordination. But if the same conduct is also under criminal investigation, the two tracks run on separate rails, and what the officer said under compulsion stays in the administrative file.
Why It Takes So Long
At least 24 states have enacted laws commonly known as a Law Enforcement Officers’ Bill of Rights, which guarantee procedural protections to officers during misconduct investigations. Nearly all require that an officer be notified when they’re under investigation and told who will be questioning them. Common additional protections include the right to counsel, restrictions on releasing the officer’s personal information to the press, protection from punitive reassignment, requirements that investigations be conducted by other law enforcement officers, and limits on which government entity can impose discipline.2National Conference of State Legislatures. Law Enforcement Officer Bill of Rights
At least 15 states also set statutory deadlines on how long an investigation may take, how far back an incident can be, and who can access the investigation records.2National Conference of State Legislatures. Law Enforcement Officer Bill of Rights Union contracts often layer on waiting periods before an officer can be interviewed and limits on how many investigators can be in the room. None of this stops investigations, but it shapes the pace and the bounds of what investigators can do.
The Four Possible Findings
At the end of the investigation, the investigator issues a finding for each allegation. Most agencies use some variation of four categories:
- Sustained. The evidence supports the allegation, judged by a preponderance standard: more likely true than not. This is the only finding that leads to discipline.
- Not sustained. There wasn’t enough evidence to prove or disprove the allegation. Many complaints land here, particularly when there’s no video and it comes down to competing accounts.
- Unfounded. The investigation concluded the incident didn’t occur as described.
- Exonerated. The conduct happened, but it was lawful and within policy.
Most complaints do not end in a sustained finding. National data suggests roughly one in seven are resolved in the complainant’s favor. The evidentiary burden sits on the complainant, many incidents lack independent witnesses or video, and the investigation is conducted by the officer’s own agency. That doesn’t make filing pointless. A not-sustained finding still goes in the officer’s file, and multiple complaints against the same officer can trigger supervisory attention or pattern-based review that no single complaint would prompt on its own.
Discipline and the Officer’s Right to Appeal
When an allegation is sustained, the discipline depends on how serious the conduct was and what the officer’s record looks like. Possible outcomes include mandatory retraining, a formal letter of reprimand, suspension without pay, demotion, and termination. These are administrative penalties, entirely separate from any criminal charges.
Officers can appeal discipline. Depending on the jurisdiction, appeals go through civil service boards, police commissions, or binding arbitration, and arbitrators overturn or reduce discipline at significant rates. An officer who was fired can be ordered reinstated by an arbitrator who concludes the department didn’t meet its evidentiary burden or didn’t follow proper procedures. The disciplinary outcome you’re told about may not be the last word.
What You’ll Learn About the Outcome
Once the investigation and any discipline are finalized, the agency notifies you. What you actually learn varies enormously. In some places you get a letter with the bare finding and nothing else. Others provide a summary of the investigative steps and the reasoning.
Laws protecting the confidentiality of officer personnel records often prohibit the agency from telling you what specific discipline was imposed, even when your complaint was sustained. Transparency laws range from states that release sustained complaints through public records requests to states that treat virtually all disciplinary information as confidential. If your letter doesn’t say whether you can appeal, ask. Some jurisdictions allow complainants to request review by a civilian oversight board or police commission when they’re dissatisfied with the result.
Other Tracks You Can Still Pursue
The internal complaint is one track. There are others, and they don’t depend on how your administrative complaint comes out.
You can report the same conduct to the federal government. For criminal misconduct, the Department of Justice directs complaints to the FBI or the U.S. Attorney’s Office in your area, both of which investigate allegations under 18 U.S.C. § 242, the federal law criminalizing willful deprivation of constitutional rights under color of law.3Office of the Law Revision Counsel. 18 USC 242 – Deprivation of Rights Under Color of Law For civil complaints, you can file through the DOJ’s Civil Rights Division at civilrights.justice.gov. The person whose rights were violated is treated as a victim and often serves as a key witness. The DOJ will generally inform you of the outcome, but it does not act as your attorney.4United States Department of Justice. Addressing Police Misconduct Laws Enforced by the Department of Justice
You can also sue. Under 42 U.S.C. § 1983, you can bring a civil action against any person who, acting under government authority, deprives you of rights protected by the Constitution or federal law, and seek money damages and injunctive relief in federal court.5Office of the Law Revision Counsel. 42 USC 1983 – Civil Action for Deprivation of Rights The lawsuit is yours to bring independently of the administrative process; a not-sustained finding does not block it. One important limit: if you were convicted of a crime connected to the same incident, the Supreme Court’s 1994 decision in Heck v. Humphrey may prevent you from suing until that conviction is overturned, because you can’t pursue a civil rights claim that would necessarily imply your conviction was invalid.
Finally, your complaint may become part of a bigger record. Under 34 U.S.C. § 12601, the Attorney General can investigate law enforcement agencies that engage in a “pattern or practice” of conduct violating constitutional rights.6Office of the Law Revision Counsel. 34 USC 12601 – Cause of Action A single complaint won’t trigger one of these civil investigations, which look for repeated or sustained misconduct indicating a department-wide problem rather than an isolated incident.7Department of Justice. FAQ About Pattern or Practice Investigations When the DOJ does find a pattern, it can seek court orders requiring reform. Your complaint becomes part of the record federal investigators draw from when they decide where to look.
One Caution on False Complaints
Many states make it a crime to knowingly file a false report with a law enforcement agency, and that includes fabricated misconduct complaints. The specific offense and penalties vary by jurisdiction. These laws target deliberate fabrication, not honest disagreement about what happened, so a good-faith complaint where your recollection differs from the officer’s account is not what the statute reaches.
