Key facts: Disorderly conduct is a misdemeanor in most states and generally requires some public element or impact, while federal law separately criminalizes inciting or organizing a riot and interfering with officers during a civil disorder.[1][2][3]

Public order crimes are offenses aimed at behavior that disturbs the peace, safety, or morals of the public, such as disorderly conduct, rioting, and civil disorder.[1]Some public order offenses are defined by state law, while others, such as certain riot-related offenses, exist under federal statute.[2][3]

Overview

Public order crimes target conduct that disturbs the peace, safety, or morals of the general public or of a group of people.[1]These offenses often overlap with other categories discussed under crimes and offenses, and the specific conduct punished, and how severely, varies by state.[1]Federal law also addresses certain public order conduct directly, including rioting and civil disorders that affect interstate commerce or federally protected functions.[2][3]Understanding how any charge is classified can matter for sentencing and procedure, as explained under felony vs misdemeanor vs infraction.

Disorderly conduct

Disorderly conduct covers behavior that causes others to become annoyed, alarmed, offended, inconvenienced, physically injured, or financially harmed.[1]Examples include being drunk in public, loitering, fighting, making loud or disturbing noises, making offensive expressions or gestures, and damaging public or private property.[1]The offense is a misdemeanor in most states and usually involves some public element or impact.[1]Related concepts include breach of the peace and willful conduct.[1]Because disorderly conduct is typically a misdemeanor, the process that follows an arrest, including arraignment and possible plea bargaining, may move differently than in a felony case.

Riot and civil disorder

Federal law separately punishes riot-related conduct that involves interstate travel or the use of interstate commerce facilities such as mail, telephone, radio, or television.[2]Under 18 U.S.C. § 2101, a person who travels in or uses such facilities with intent to incite a riot, to organize, promote, encourage, participate in, or carry on a riot, or to commit or aid an act of violence in furtherance of a riot, and who performs some overt act for that purpose, can be fined or imprisoned for not more than five years, or both.[2]A conviction or acquittal on the merits under state law bars a later federal prosecution under this statute for the same act or acts.[2]The statute also states that it does not make it unlawful to travel or use commerce facilities to pursue the legitimate objectives of organized labor through orderly and lawful means, and it does not prevent states from exercising their own jurisdiction over the same conduct.[2]A related statute, 18 U.S.C. § 231, addresses civil disorders, making it unlawful to teach or demonstrate the use of a firearm or explosive or incendiary device, or to transport or manufacture one for transportation in commerce, knowing or intending it will be used unlawfully in furtherance of a civil disorder that obstructs commerce or a federally protected function.[3]That statute also punishes committing or attempting to obstruct, impede, or interfere with a fireman or law enforcement officer lawfully performing duties during a civil disorder that affects commerce or a federally protected function, with the same maximum penalty of a fine or five years' imprisonment, or both.[3]The statute does not make unlawful any act by a law enforcement officer performed in the lawful performance of official duties.[3]These federal provisions can apply alongside, rather than instead of, state and local offenses, since the riot statute notes it is not meant to strip state and local authorities of responsibility for prosecuting violations of their own law.[2]Readers facing either state or federal public order charges may find it useful to review federal crimes and the general outline of the criminal process step by step.

Free speech limits

Disorderly conduct can include making offensive expressions or gestures, which means these laws sometimes intersect with expressive or communicative conduct.[1]Because the offense generally requires some public element or impact, and definitions of disorderly conduct vary by state, the line between punishable conduct and protected expression is not uniform.[1]Anyone weighing how a particular public order statute applies to expressive conduct may want to review the broader constitutional protections summarized under constitutional rights of the accused and the criminal defenses that can be raised in a given case.

Common questions

What are public order crimes?

Public order crimes are offenses involving conduct that disturbs the peace, morals, or safety of the public or of a group of people, such as being drunk in public, loitering, fighting, or making loud or disturbing noises.[1]Some public order conduct, such as inciting a riot or interfering with officers during a civil disorder, is also addressed directly by federal statute.[2][3]

Are they usually misdemeanors?

Disorderly conduct is a misdemeanor in most states and usually involves some public element or impact.[1]Federal riot and civil disorder offenses are more serious, carrying a fine or imprisonment of not more than five years, or both[2][3], so grading can depend on which law applies, a distinction discussed further under felony vs misdemeanor vs infraction.

Can disorderly conduct charges involve property damage?

Yes, examples of disorderly conduct include damaging public or private property, alongside behavior such as public drunkenness and fighting.[1]

Does a state riot case bar a federal riot prosecution for the same act?

Under 18 U.S.C. § 2101, a judgment of conviction or acquittal on the merits under state law is a bar to a federal prosecution under that statute for the same act or acts.[2]

Does the federal civil disorders law apply to police officers doing their jobs?

No; 18 U.S.C. § 231 states that nothing in it makes unlawful any act of a law enforcement officer performed in the lawful performance of official duties.[3]

Do public order laws always target protest activity?

The sources describe disorderly conduct as general public-disturbance behavior such as public drunkenness, loitering, and fighting, and describe riot and civil disorder statutes as addressing incitement, organizing violence, or interfering with officers during a disorder; none of the sources state that these laws are limited to protest activity.[1][2][3]
