Inconsistent data isn't just a headache in the criminal justice system -- it could make the difference between someone going free or serving time. California might do something about that soon, though. The state legislature has passed a bill, AB-1331, that would improve data handling for criminal justice. The measure would set clear data collection and reporting standards for both the courts and law enforcement, such as a requirement that agencies hand over criminal ID and information, incident and court numbers. It would also let courts share some data with researchers hoping to interpret justice data and hold officials to account.
