Potioncat:
No you are not off base. The question is, how many DEs knew that Peter 
was the informer? The ones in Azkaban were not able to communicate with 
the ones who walked free. Although Snape is obviously a double agent (I 
think that's the right term) he may not have known it was Peter who 
betrayed the Potters. Several of his comments place him in the Sirius-
as-traitor camp.

We've seen at one, maybe two situations where he seems out of the DE 
loop. I say "seems" because we really can't know. One is the DoM plan 
and the other is the Vanishing Cabinet mission. It's hard to tell when 
he's been kept in the dark and when he's pretended not to know. 

Potioncat...who really is making a pie.
