In what way did Google defame this man? First it was established by a court of law whether the statement, the suggestion, the search term, whatever in itself was false or not. Whether it was defamation or not. It obviously was defamation! The next phase would be, who was responsible for publishing the content. Google. PERIOD. On top of that Google didn't remove the content when requested, which makes them more liable. Let's note here that in this case they ARE the PUBLISHER NOT the MEDIUM!
This is not about "suggestions" or "assertions" but about who was the one responsible for the publishing of the defamatory content and that was ole GOOGLE! Let's not look for the 5th leg of that cat here. There ain't one! Oh wait, there is this cat on youtube :-)
Sorry Demaestro, you da man! I'm out! I'm crawling back under that rock! Too hungry for this.
