Arnold Kim of Macrumors.com generally sticks to the speculative evidence, usually refraining from venturing into wilder guesses. Recently he brought to light an obvious but somehow ignored pattern: 1) Apple Legal never gets involved for Images/Video of Fake Products and 2) Apple Legal always gets involved for Images/Video Real Products. Apple Legal could be the best way to verify leaked images, since they can only C&D property that is theirs. I call the pair Arn's First and Second Law of Apple Rumors. Easy, no?
He backed up his observation with historical -although selective- evidence. There have been times in the past in which Apple hasn't retired images of their intellectual property. Other times, they have retired things which never materialized because it contained Apple's IP. If he's right, we may all have an astoundingly accurate method of determining which leaked images are fake and real. If he's wrong, we wouldn't be surprised either. He timepegs his theory to the recent iMac keyboard, which contrary to popular belief, he thinks is fake.
Whatever happens, our recommendation is that you follow The Giz's Own Theory of General Apple Rumors Relativity: never ever trust rumor sites. Why? For exactly the same reasons you don't trust fortune tellers, astrology experts and goat-entrails readers. [NormalKid]
