Two decades ago, if a county wanted to update someone’s criminal record, a clerk had to put a piece of paper in a file. And if you wanted to read about someone’s criminal past, you had to walk into a courthouse and thumb through it. Today, half the courts in the United States put criminal records on their public websites.
Digitization was supposed to make criminal records easier to access and easier to update. To protect privacy, laws were passed requiring courts to redact some information, such as birth dates and Social Security numbers, before they put records online. But digitization perpetuates errors.
