Missouri Revised Statutes Title XXXVIII. Crimes and Punishment; Peace Officers and Public Defenders § 577.712. Refusal of admission to terminal--requests for identification or to leave terminal authorized, failure to comply, penalty

1. In order to provide for the safety, comfort, and well-being of passengers and others having a bona fide business interest in any terminal, a bus transportation company may refuse admission to terminals to any person not having bona fide business within the terminal. Any such refusal shall not be inconsistent or contrary to state or federal laws, regulations pursuant thereto, or to any ordinance of the political subdivision in which such terminal is located. A duly authorized company representative may ask any person in a terminal or on the premises of a terminal to identify himself or herself and state his or her business. Failure to comply with such request or failure to state an acceptable business purpose shall be grounds for the company representative to request that such person leave the terminal. Refusal to comply with such request shall constitute disorderly conduct. Disorderly conduct shall be a class C misdemeanor.

2. It is unlawful for any person to carry a deadly or dangerous weapon or any explosives or hazardous material into a terminal or aboard a bus. Possession of a deadly or dangerous weapon, explosive or hazardous material shall be a class D felony. Upon the discovery of any such item or material, the company may obtain possession and retain custody of such item or material until it is transferred to the custody of law enforcement officers.
