Public Alarm Under Oregon’s Riot Statute ORS 166.015

The element Oregon law calls a grave risk of causing public alarm

Oregon’s riot statute provides that a person commits riot if, while participating with five or more other persons, the person engages in tumultuous and violent conduct and thereby intentionally or recklessly creates a grave risk of causing public alarm. ORS 166.015.

The statute itself does not define the phrase public alarm. Oregon appellate courts have therefore supplied the governing meaning, and those decisions make clear that public alarm is a narrower concept than everyday annoyance, offense, or emotional discomfort. The cases consistently tie the element to fear arising from perceived physical danger and to conduct that threatens an imminent breach of the peace.

The foundational Oregon definition of public alarm

The leading interpretation of public alarm in the riot context comes from State v. Chakerian. The Oregon Court of Appeals explained that the term alarm refers to fear or terror resulting from a sudden sense of danger and does not reach conduct that causes mere psychic discomfort. The court further explained that public alarm is collective and communal, rather than individual and innately idiosyncratic. State v. Chakerian, 135 Or App 368 (1995).

On review, the Oregon Supreme Court agreed with that framing and emphasized that ORS 166.015 is directed at a harm, not at speech. The court stated that the statute is not directed at restraining expression, but rather at the creation of a grave risk of public alarm through specified conduct. State v. Chakerian, 325 Or 370 (1997).

The Supreme Court also addressed vagueness concerns and explained that the phrase grave risk of public alarm must be read together with the requirement that the conduct be tumultuous or violent. When read as a whole, the statute adequately informs citizens of the prohibited conduct. Giving the statute a fair reading in light of the common meanings of tumultuous, violent, and conduct, the court concluded that ORS 166.015 refers to physical activity that reasonably is perceived by others as threatening an imminent breach of the peace. State v. Chakerian, 325 Or 370 (1997).

How Oregon courts apply the public alarm element

Oregon appellate decisions applying the riot statute show that public alarm is not satisfied by mere attention, curiosity, or spectatorship.

In State v. Hicks, the Court of Appeals held that more is required to sustain a riot conviction than simply a showing that bystanders or spectators gathered around a fight. State v. Hicks, 120 Or App 345 (1993).

By contrast, in State ex rel. Juvenile Dept. of Washington County v. Saechao, the court found the element satisfied where an attack occurred in a crowded school hallway. The court emphasized that the conduct risked a greater melee, injury to noncombatants, and the natural alarm flowing from both risks. State ex rel. Juvenile Dept. of Washington County v. Saechao, 167 Or App 227 (2000).

These cases illustrate that the inquiry focuses on the risk created by the conduct itself, including the risk of escalation and harm to others, rather than on whether people merely noticed or gathered.

Jury instructions and common understanding

Oregon courts have also treated public alarm as a term that may be left to its commonly understood meaning at trial. In State v. Lewis, during jury deliberations the jury asked for a definition of public alarm. The trial court declined to provide an additional definition and instructed the jury to view the term as carrying its commonly understood meaning. The Court of Appeals affirmed. State v. Lewis, 335 Or App 685 (2024).

Guidance from analogous Oregon alarm cases

Oregon courts have construed the term alarm consistently across multiple criminal statutes, reinforcing a narrow understanding tied to fear of physical danger rather than annoyance or emotional distress.

In the harassment context, the Oregon Supreme Court held that alarm means more than mere inconvenience or feelings of anguish resulting from angry or imposing words. Instead, it means being placed in actual fear or terror resulting from a sudden sense of danger. State v. Moyle, 299 Or 691 (1985); ORS 166.065(1)(d).

In the intimidation context, the Court of Appeals has explained that the term alarm limits the statute to more than mere inconvenience or anguish and requires fear tied to serious physical injury. The statute reaches only unequivocal and unambiguous threats of such harm. State v. Smith, 319 Or App 388 (2022).

In the stalking protective order context, the Court of Appeals defined alarm as causing apprehension or fear resulting from the perception of danger, with danger referring to a threat of physical injury rather than a threat of annoyance or harassment. D O v. Richey, 301 Or App 18 (2019); Or Rev Stat §§ 163.730(1), 163.738.

These decisions reflect a consistent judicial understanding that alarm is grounded in fear of physical danger, not subjective offense or discomfort.

Constitutional limits on riot prosecutions

The constitutional backdrop reinforces these limits. In Chakerian, the Oregon Supreme Court made clear that ORS 166.015 is conduct based and not directed at speech. State v. Chakerian, 325 Or 370 (1997).

That conduct based focus distinguishes the riot statute from provisions struck down under Article I, section 8 of the Oregon Constitution. In State v. Spencer, the Oregon Supreme Court invalidated a disorderly conduct provision that criminalized the expression or speaking of certain kinds of language when done to cause public inconvenience, annoyance, or alarm. State v. Spencer, 289 Or 225 (1980); ORS 166.025(1)(c).

Riot prosecutions must therefore remain anchored to tumultuous and violent conduct that creates a grave risk of public alarm, rather than drifting into punishment of expressive activity.

Summary

Under Oregon law, public alarm in the riot statute is a collective and objective concept. It requires fear or terror arising from a perceived risk of physical danger and must be created by tumultuous and violent conduct that reasonably threatens an imminent breach of the peace. Mere annoyance, psychic discomfort, or the fact that people gather or observe is not enough.
