Do you really, then why didn't Wormtail kill Harry right under Dumbledores nose, a small feat if someone can get away with being one of Voldemorts servants under Dumbledores eyes.
Really, how could they. The students live at Hogwarts, as do the teachers. I am sure Dumbledore has a very good idea of what people are working with him and against him. Which is why I don't think Snape is a death eater, unless Dumbledore is one himself, which would be a very interesting turn of events.
