Missouri’s state law requires that all peace officers in the state report specific information including a driver’s race for each vehicle stop made in the state. Law enforcement agencies are required to turn in the data to the Attorney General, and the Attorney General is required to compile the data and report to the Governor no later than June 1 of each year. The law allows the Governor to withhold state funds for any agency that does not comply with the law.
