You mustn't judge a law only by its best results, but by all of them, and particularly by its unintended consequences.
A murder or felony is never spent under rehabilitation acts and thus the status of it never changes or expires. The judgement addressed the relevancy of information according to time, and time doesn't make murder less relevant. Of course Google would be fine to continue to return this in their results. Did you read the judgement?
