Suspecting is quite different from knowing, and I can't blame you at all for keeping quiet when you had no proof. But at least one person on this post has admitted to knowing for sure since not long after it happened, and it seems that several people had proof and remained silent. Those were the ones my lack of warm fuzzies comment was directed towards, because I can honestly say that I, personally, find it inexcusable, regardless of why they did it.
