Civil Disorder: Federal Law, Prohibited Conduct, and Penalties

Under federal law, civil disorder is a specific criminal offense defined in 18 U.S.C. § 232 and prohibited by 18 U.S.C. § 231. It covers violent conduct by a group of three or more people that threatens or causes injury to others or their property, when that disturbance affects interstate commerce or a federal government function. A conviction carries up to five years in prison and a fine of up to $250,000 for an individual.

What Actually Counts as Civil Disorder

The statutory definition sits in 18 U.S.C. § 232. Civil disorder is any public disturbance involving acts of violence by a group of three or more people that causes an immediate danger of harm, or actually results in damage or injury, to another person or their property.¹

Every element carries weight. One person acting violently doesn’t qualify. A group gathering peacefully doesn’t qualify. Property damage without a group component doesn’t qualify. The violence has to come from an assemblage, and it has to threaten or cause real harm. A loud, disruptive protest that blocks traffic but involves no violence sits outside the definition entirely. So does a large bar fight, unless it rises to a public disturbance threatening injury to bystanders or their property.

The Federal Hook

Having a civil disorder isn’t enough for federal charges. Prosecutors also have to show a federal nexus: the disturbance must obstruct, delay, or adversely affect either interstate commerce or a federally protected function.² Without that connection, the conduct stays with state or local prosecutors.

The statute reads “commerce” broadly, taking in trade between states, trade that passes through another state, and commerce within the District of Columbia. A “federally protected function” covers any operation carried out by a federal department, agency, or employee under federal law, and specifically includes U.S. mail collection and distribution.¹ In practice, prosecutors don’t struggle with this element. A disturbance that shuts down a highway used for interstate shipping, disrupts a federal courthouse, or blocks mail delivery clears the bar.

The Three Categories of Prohibited Conduct

Section 231 reaches beyond the people swinging fists at the scene. It targets three separate categories of conduct, and a person can be charged under any one of them.

Teaching or Demonstrating Weapons Techniques

Instructing another person on how to use, build, or apply a firearm, explosive, incendiary device, or any technique capable of causing injury or death is an offense when the instructor knows, has reason to know, or intends that the instruction will be used unlawfully to further a civil disorder.² This reaches people who never show up at the disturbance. Running a workshop on building incendiary devices for protest use could support a charge even if the instructor stays home that day.

Transporting or Manufacturing Weapons

Moving or producing firearms, explosives, or incendiary devices for transport in commerce is a separate offense when the person knows or intends they will be used unlawfully to further a civil disorder.² The provision targets the supply chain. Driving a truckload of Molotov cocktails across state lines to arm participants at a planned confrontation is the kind of conduct it captures.

Interfering with Law Enforcement or Firefighters

Committing or attempting any act that obstructs or interferes with a firefighter or law enforcement officer during a civil disorder is the third category.² The officer must be lawfully performing official duties connected to the disorder, and the disorder itself must satisfy the federal nexus requirement. This is the subsection prosecutors have leaned on most in recent years, including in hundreds of cases arising from the January 6 Capitol breach, where defendants were charged for pushing against police lines, pulling away barricades, and throwing objects at officers.

The statute’s definition of “law enforcement officer” is wide. It includes any federal, state, or local government employee engaged in enforcing criminal law, plus National Guard members, state militia, and members of the Armed Forces while they are suppressing violence or restoring order during a civil disorder.¹ Interfering with a National Guard soldier deployed to contain a riot carries the same charge as obstructing a city police officer.

What the Government Has to Prove About Your State of Mind

Each category has its own knowledge-or-intent requirement, and this is where many prosecutions turn. For the teaching and transport provisions, the government must prove the defendant acted “knowing or having reason to know or intending” that the weapons or instruction would be used unlawfully to further a civil disorder.² That language gives prosecutors three routes: actual knowledge, constructive knowledge (you should have known), or specific intent.

The interference provision works differently. The prosecution has to show the defendant committed or attempted an act designed to obstruct or interfere with officers, but the statute does not require proof that the defendant meant to further the broader disorder. The obstruction itself is the crime. What often becomes the harder question is whether the officer was “lawfully engaged” in official duties at the time. In at least one early case arising from the 1973 Wounded Knee occupation, a court acquitted defendants after finding evidence that law enforcement may not have been acting lawfully during the confrontation.

Prison Time, Fines, and How Charges Stack

A conviction under any subsection of 18 U.S.C. § 231 carries a maximum prison sentence of five years, a fine, or both.² The statute says “fined under this title” without setting a dollar amount, so the general federal fine provision controls. For an individual convicted of a felony, the maximum fine is $250,000. An organization convicted of the same offense faces fines up to $500,000.³

The U.S. Sentencing Commission has not established a specific guideline for civil disorder offenses under § 231(a)(3), so sentencing courts have more discretion than usual. Judges weigh the general sentencing factors: the nature and seriousness of the conduct, the harm caused, and the defendant’s criminal history. Civil disorder counts often ride alongside other federal offenses, such as assault on a federal officer or destruction of government property. Those have their own ranges, and consecutive sentences can push the total well beyond five years.

Where the Line With Protest Sits

The statute lives in tension with the First Amendment. Peaceful protest, however disruptive or unpopular, is constitutionally protected. The “acts of violence” requirement is what keeps § 231 from becoming a tool for suppressing dissent, and the boundaries get contested in practice.

The teaching provision is the most constitutionally sensitive. Pure speech, even speech about how weapons work, is generally protected. The statute narrows its reach by requiring proof that the instructor knew or intended the information would be used unlawfully to further a civil disorder. Abstract advocacy of violence, without a direct connection to imminent lawless action, stays protected under longstanding Supreme Court precedent. A professor lecturing on the chemistry of explosives in a classroom isn’t committing civil disorder. Someone running a bomb-making tutorial for people planning to attack a federal building might be.

Defense attorneys often argue that a client was engaged in protected protest that happened to occur near violence the client didn’t participate in. The government’s burden to prove the defendant’s specific conduct and mental state is the main safeguard. Being present at a protest that turns violent is not, by itself, a federal crime.

What a Conviction Costs Beyond the Sentence

Civil disorder under § 231 is a federal felony, and the collateral consequences run well past the prison term and fine. For many defendants these matter more than the sentence.

Firearms: Federal law prohibits anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition. A civil disorder conviction triggers this lifetime ban.⁴
Voting rights: Federal law does not strip voting rights, but most states restrict or suspend voting for people with felony convictions. Rules vary widely, from automatic restoration after release to permanent disenfranchisement without a governor’s pardon.
Employment: A federal felony conviction appears on background checks and can disqualify a person from government employment, security clearances, and many professional licenses. Law enforcement, education, and financial services routinely screen for felony records.
International travel: Many countries deny entry to people with serious criminal convictions. Canada, Australia, New Zealand, and the United Kingdom all allow border authorities to refuse travelers based on criminal history, often tied to whether the person received a sentence of 12 months or more.

None of these consequences expire on their own. Unlike the prison sentence, a federal felony record follows a person through employment applications, housing screenings, and border crossings unless pardoned or expunged through the narrow federal processes available.

Not to Be Confused With Nearby Federal Charges

Federal law contains several overlapping public-order offenses, and civil disorder is not the same as any of them. The federal Anti-Riot Act, 18 U.S.C. § 2101, targets a person who travels in interstate commerce or uses an interstate facility with the intent to incite, organize, encourage, or participate in a riot, then takes a concrete step toward that goal; it also carries up to five years.⁵ Insurrection under 18 U.S.C. § 2383 is a more serious charge, reaching anyone who incites, assists, or engages in rebellion against the authority of the United States, and it carries up to ten years plus a permanent bar from federal office.⁶ State rioting and unlawful assembly statutes cover much of the same territory without any federal connection, which is why the same event can produce parallel state and federal cases against different defendants.
