Hello? Are we forgetting that the entire point of a prison sentence is that after that, it is FORGIVEN?
Because ANYONE should have the ability to leave his past behind, and become an upstanding citizen again. Even serial killers. (Example: Somebody with a neuro-chemical imbalance that self-corrected when he got older. Like, e.g. every schizophrenic person with the right kind of delusions.)
That is the entire problem with recording people: Somebody can still hate and terrorize you, *decades* after you've already been forgiven.
That is why there's a right to privacy, even in public, in the GDPR. That's its whole point.
So no, Wikimedia, you can not go around, dragging people back down to their bad past. Because then YOU will be responsible for further harm to everyone.
Handle it like criminal records: Secret, unless specifically demanded.
That way, you can have it both ways. Not be censored, but also not cause harm yourselves.
(Of course Americans might not get any of this. I always see them casually running around Germany, "vlogging" random people on the street. Until they get the cops called on them. lol)
