Re: Forgotten what?
The whole point is that the right is not a blanket "I don't like this. Take it off the internet". The problem is that, search engines specifically, are not clever enough. They aren't nuanced enough to construct and proper and accurate time line to realise that the very newsworthy arrest you experienced ten years ago was followed by the case being thrown out or never prosecuted.
Many jurisdictions also have convictions expire after a time, once the fin has been paid or time served. The "right to be forgotten" doesn't mean all this magically disappears from history, it just means that search engines have to be much more careful about what they present in search results and, additionally, have to conform to local custom, law and (cultural) standards/expectations, e.g. do you consider the legal/justice system to be punitive or reformative? The answer to that will often determine which side of the fence you're sitting on the right to be forgotten.
