Almost every state in the
United States has a
disorderly conduct law that makes it a crime to be drunk in public, to "disturb the peace", or to loiter in certain areas. Many types of unruly conduct may fit the definition of disorderly conduct, as such statutes are often used as "catch-all" crimes. Police may use a disorderly conduct charge to keep the peace when people are behaving in a disruptive manner to themselves or others, but present no serious public danger. Disorderly conduct is typically classified as a
misdemeanor.
A typical statutory definition of disorderly conduct, in this case Indiana's, defines the offense in this way
Indiana's definition of "disorderly conduct" is modeled after the Model Penal Code's definition, and is typical, but not identical, to similar laws on the statute books of other U.S. states. It covers a large variety of potential acts in its prohibition; "fighting" is perhaps the clearest act within the scope of its prohibition. What is "tumultuous conduct," what constitutes "unreasonable noise", or what "disrupts a lawful assembly" are matters that are far harder to decide, and as such disorderly conduct statutes give police officers and other authorities fairly broad discretion to arrest people whose activities they find undesirable for a wide variety of reasons. Potential punishments include a jail term, fine, probation, restraining orders, or community service.
The courts confronted with cases stemming from these arrests have from time to time had occasion to restrict the broad and vague definitions of the statute to make certain that freedom of speech and assembly and other forms of protected expression under the First Amendment were not affected.[2] They also have had occasion to curb its scope to make certain that people were (or could have been) aware that their conduct was, in fact, within the prohibition of the statute, as required by the due process clause of the Fourteenth Amendment. However, no court has struck down a disorderly conduct statute as being per se unconstitutionally vague or overbroad. Courts have been willing to strike down vagrancy ordinances which are nearly as vague and do not give adequate warning.
