These lines are LexLint's reading of the law's text.
In the frameworks
- NIST AI RMF
- MAP 4.1Approaches for mapping AI technology and legal risks of its components – including the use of third-party data or software – are in place, followed, and documented, as are risks of infringement of a third party’s intellectual property or other rights.
Our reading of where this law's duties sit in each framework, and in the NIST AI RMF, line by line beside each duty above. It never says that running a control meets the law. How we read a framework against the law
If you get it wrong
Criminal exposureYes
Criminal exposure note
A class A misdemeanor (up to one year in jail), rising to a class E felony where the conduct is committed to defraud or obtain property worth 750 dollars or more, or (for computer-equipment tampering) causes damage of 750 dollars or more, and to a class D felony where equipment damage reaches 25,000 dollars or more.
What it makes you log
Logging duty
Section 569.095 defines tampering with computer data (modifying or destroying data or programs, disclosing or taking data or passwords, accessing and examining information about another person, and receiving or using data obtained in violation). The page the row cites holds only this section; sections 569.097 and 569.099 are not on it and are left out of this answer. Section 569.095 imposes no duty to create, keep, produce or review a log or record and states no territorial clause, so no hook is recorded.

What this law does
A person commits tampering with computer data, computer equipment, or computer users if, knowingly and without authorization or without reasonable grounds to believe he or she has authorization, the person modifies, destroys, discloses, or takes computer data, programs, or supporting documentation; discloses or takes a password or other information controlling access to a system; accesses a computer and intentionally examines information about another person; accesses, modifies, destroys, damages, or takes computer equipment or a computer, system, or network; or denies computer system services to an authorized user.
Each offense is a class A misdemeanor unless committed to defraud or obtain property worth 750 dollars or more, or (for tampering with computer equipment) causes damage of 750 dollars or more, in which case it is a class E felony, rising to a class D felony where the equipment damage reaches 25,000 dollars or more.
The without-authorization test is undefined by the statute and, unlike Virginia's parallel statute, carries no separate requirement of malicious intent or intentionally deceptive means; no Missouri appellate decision was located applying it to automated collection of a public, unauthenticated web page.
