Dumbledore's dead? Really? Wow! How come no one's bothered to tell me that?

A question though. And a few words before that. It's not Dumbledore's death that bothers me really. Twas in harmony with the trend that JKR started of killing off Harry's guardians one by one. And the plot she led up to sort of needed it. Dumbledore was the one person that Voldy feared, so he kinda had to go to make way for Voldy to announce himself and for Harry to face him alone at a stage like Hogwarts. Well, anyway, I kinda hoped that he'd be alive and thus my siggy says what it says, and it's been saying that for so long that I didn't bother changing it, and don't think I will. My question is actually concerning Snape.

If I'm not terribly mistaken, the last thing that Snape had to ensure for Dumbledore was that Voldy and Harry met face to face in a fight. If Snape had been successful in bringing Harry out to meet Voldemort, and let's say that Harry got the better of his opponent, could Snape have been able to convince anyone that he had been acting under Dumbledore's wishes? Would he have tried to convince anyone of that? Would he have made his memories available then for others to see?

Been out of the general discussion forums for a while. The Snape thing just pricked me, so I asked. If the question has been asked somewhere already, and answered, point me in the right direction please..

I initially thought that GOI stood for Group Of Infants.. sorry.. just came in to see if I was right..I was wrong.. the thread's about a really old dead guy..
