Recording Police in Missouri: One-Party Consent and the Wire Communication Limit

Start with what the statute actually protects. Mo. Rev. Stat. § 542.400(12) defines a "wire communication" as one made in whole or in part through facilities transmitting by the aid of wire, cable or other like connection. Section 542.402.1(1) makes it a class E felony to knowingly intercept one. A phone camera aimed at a traffic stop is capturing sound waves in the open air, not a wire communication, so subdivision (1) never engages.

In-person speech falls under the separate definition in § 542.400(8): an "oral communication" is one "uttered by a person exhibiting an expectation that such communication is not subject to interception under circumstances justifying such expectation." Two things follow. First, the expectation has to be justified, and an officer speaking to a driver on a public roadway is not in that position. The Revisor prints the point directly under the definition in the case note to Angel v. Williams, 12 F.3d 786 (8th Cir. 1993), where city officials recorded a conversation between an inmate and police officers in a public jail and the court held the officers could not justifiably have an expectation of privacy. Second, even a genuine oral communication is only criminally intercepted under § 542.402.1(2) where the device "transmits communications by radio or interferes with the transmission of such communication." A phone recording to internal storage does neither.

Missouri is a one-party consent state, and § 542.402.2(3) is where that lives: it is not unlawful for a person not acting under law to intercept a wire communication where that person is a party to the communication or where one party has given prior consent, unless the interception is for the purpose of committing a criminal or tortious act. If an officer is talking to you, you are a party. The only carve-out is purpose based, so recording to gather evidence of how a stop went is squarely lawful while recording to blackmail somebody is not.

The pressure point in Missouri is the interference offense, not the wiretap law, and the General Assembly narrowed it recently. Mo. Rev. Stat. § 575.150.1(2), as rewritten by H.B. 495 effective August 28, 2025, makes it an offense to interfere with the arrest, stop or detention of another person only "by using or threatening the use of violence, physical force or physical interference." Filming from the pavement is none of those three. Subdivision (1), covering your own arrest, is limited to violence, threatened physical force, or fleeing. Section 575.150.4 removes any defense that the officer was acting unlawfully, so the safe course is to keep recording and keep your distance rather than to argue. A first violation of § 575.150 is a class A misdemeanor, carrying up to one year in jail under Mo. Rev. Stat. § 558.011.1(6) and a fine up to two thousand dollars under § 558.002.1(2). Section 575.145 separately makes it a class A misdemeanor to refuse a law enforcement officer's reasonable signal or direction in directing traffic, which is how a lawful order to step back off a roadway is enforced.

One Missouri limit does apply to what you point the camera at. Mo. Rev. Stat. § 565.252.1(1) makes it invasion of privacy, a class A misdemeanor, to knowingly create an image of another person without consent while that person is in full or partial nudity in a place where one would have a reasonable expectation of privacy. Distributing such an image, or capturing more than one person in the same course of conduct, raises it to a class E felony under § 565.252.2. A search or arrest inside a home can put a bystander in that position, so the statute is worth knowing before you livestream through a doorway.

Getting the officer's own footage is a separate exercise governed by the Sunshine Law. Mo. Rev. Stat. § 610.100.1(6) defines a "mobile video recorder" to include both in-car systems and body-worn cameras, and § 610.100.2(2) makes mobile video recordings closed records until the investigation becomes inactive. Section 610.100.1(8) defines a "nonpublic location" as a place where one would have a reasonable expectation of privacy, including a dwelling, school or medical facility, and § 610.100.2(4) lets an agency keep recordings made there closed, subject to an express right: a person depicted in the recording or whose voice is in it, that person's parent or guardian if a minor, a family member within the first degree of consanguinity if the person is deceased or incompetent, an attorney, or an insurer may obtain "a complete, unaltered, and unedited copy" on written request.

Nothing in Missouri's wiretap chapter reaches open-air recording of an officer performing public duties, so there is no charge to answer for the act of recording itself. Where a Missouri recording case does arise it is usually charged as resisting or interfering under Mo. Rev. 145, a class A misdemeanor. 1(2). 2 supplies a civil action to any person whose wire communication is intercepted, with actual damages or liquidated damages of one hundred dollars per day of violation or ten thousand dollars, whichever is greater, plus punitive damages for a willful violation and reasonable attorney's fees.

Those provisions are aimed at intercepting wire traffic, not at filming a public encounter. 6 puts the burden on the state, and Mo. art. I, § 15, as amended on August 5, 2014, expressly extends the warrant requirement to "electronic communications and data" and requires a warrant to describe the data to be accessed. 5(1) in the circuit court, which weighs the public benefit, the private matters disclosed, the risk of shame or humiliation, and whether the recording was made where a person had a reasonable expectation of privacy.

5(6) the court may charge the requester with costs and attorney fees, but may instead assess them against the agency if its refusal was substantially unjustified.
