What must be done if an error is discovered in ACJIS data?

If an error is discovered in ACJIS data, the correct action is to notify the relevant agency to correct the information. This process is crucial because it ensures that the data integrity within the system is maintained. Accurate data in law enforcement databases is vital for effective decision-making, public safety, and justice. By reporting the error to the appropriate agency, it can be investigated and rectified according to established procedures, which helps uphold the reliability of the criminal justice information system.

The other options do not represent appropriate actions for handling data errors. Reporting to the local news media would potentially spread misinformation rather than resolve the issue. Ignoring a minor error compromises the integrity of the data and could lead to larger, unintended consequences down the line. Finally, suggesting that only law enforcement can address it implies a limitation on the responsibilities of various stakeholders in the agency, as it is often a collaborative effort to maintain data accuracy.
