Mo. Rev. Stat. § 84.230
The commissioners of police shall cause all persons arrested by the police to be brought before some proper judge within said cities, to be dealt with according to law. Proper police officers in charge of police station houses may, if the offense charged against any person is a bailable one, at the request of such person, take from him a recognizance in such sum as may seem to be sufficient and proper with sufficient sureties for his appearance at the proper time before some judge, but no attorney at law, police officer, and no official or employee holding office under the municipality of the said cities, or the state of Missouri, and no clerk in the employ of such officer, officials or employees shall be accepted as surety upon such bond or bonds; the proper officers in charge of said station houses may administer oaths to parties qualifying as such surety or sureties; and may refuse to receive as such surety or sureties any and all parties with unsavory reputations or who, as professional bondsmen, tend to defeat the ends of justice, and no one shall be accepted as bondsman who shall have standing against him an unsatisfied judgment rendered on a forfeited bond; such proper police officers in charge of police stations may, prior to the appearance of any person arrested before some proper judge, refuse to admit to the presence of arrested persons confined in stations, all persons who have the reputation of being what is known as grafters or shysters, or those attorneys who are guilty of the practice of soliciting business.
