I don't think you have to be a criminal to be in some sort of police database. And even if it did mean that, it should make no difference as to how their privacy is treated. If anything, a police database should have higher bars to third party access on privacy grounds than almost any other kind of database. The only thing that should be public are court records.

Furthermore, I firmly believe court records should not be public en masse but rather only individually. It should not be trivial to just check a name and see if they've been convicted of something. Sentence served should mean you don't have lingering repercussions.

There's a balance there - the court records need to be public so that the justice system can be held accountable by the public in some way, and records need to be available to inform precedent for future decisions. That needs to be weighed against what you mentioned, the impact of the availability of those records on the people they are about.
