The unfortunate fact is that quite often, there are no "teeth" which could force a foreign-based party to take down inappropriate information directly so that it would not be displayed in Google's search results. 

There is an entire industry out there of foreign (sometimes U.S.)-based websites on which people can anonymously publish vicious lies about someone and the website will hide behind the U.S. Communications Decency Act in refusing to remove it. So one day you could wake up and one of the top search results for your name will say that you are a child molester and there will be nothing you'd be able to do about it. 

Forcing Google to remove those search results is the proper way to go. After all, the only reason anyone even knows these defamatory websites exist is because Google displays them in its search results. 

The E.U. certainly got this one right and I hope so does our Supreme Court.
