It’s a difficult balance. On one hand, privacy is important. On the other hand, visibility into the system is an important check on the power of law enforcement. It’s especially important for arrests; you really, really do not want the police to be allowed to secretly jail people. But it’s important for other things too. In this example, if the police were using rollerblading citations as a way to harass a certain group of people, it’s good to have access to that information to be able to discover this.
