We as a society have decided to keep public records. I don't see anyone advocating that we clean everyone's record after they repay their debt to society. We still have background checking services and they don't have to enforce a right to be forgotten. I assume county record searches don't have to enforce a right to be forgotten. I also assume a specifically focuses criminal record website doesn't have to enforce a right to he forgotten. It seems a little weird to enforce it on Google under some pretence that he should have a clean record after repaying his debts to society.
