Mike:

I'd like to answer you with another's post:

>From message # 159701, Nikkalmati:
Query: Why would DD allow SS to walk out of the Hog's Head with that
information? He hired ST as Divination teacher to protect her from
LV, so he realized the importance of the prophecy. Aberforth had SS
by the collar. Why would DD let him go? 

Mike again:

Now, I invite anyone to answer this question:

Why doesn't Dumbledore hit Snape with an "Obliviate" and erase any 
memory of the prophesy from Snape?

I can't see how anyone can come up with a credible reason for Albus 
and Aberforth to let Snape-the-still-faithful-DeathEater leave with 
this knowledge intact to deliver to Voldemort. Not when there is 
such an easy answer to the problem at hand. I've been surprised 
before, anyone want to give this one a shot?

Mike, acknowledging Nikkalmati's most elegant yet simplisticly 
beautiful question <Bg>, while still intending to defend Dumbledore
(coming soon, to a theatre... I mean list... near you)
