Missouri Disorderly Conduct Laws

Missouri has an entire section for a variety of offenses that constitute disorderly conduct. This chapter - called "Offenses Against Public Order" - covers Missouri public safety violations including the typical disturbing the peace and drinking in public laws as well as more specific laws on other public safety issues such as rioting, refusing to disperse after an unlawful assembly or riot, and making terrorist threats.

The most serious offense under this chapter is causing catastrophe, which is defined as knowingly causing a catastrophe by explosion, fire, collapse of a building, or release of a dangerous and difficult to confine substance. For purposes of the statute, catastrophe is defined as causing death or serious physical injury to ten or more people, or causing substantial damage to five or more buildings or to a vital public facility. Causing a catastrophe is a class A felony, which is punishable by imprisonment for ten to 30 years, and in some cases life in prison.
