Potioncat:
I agree with Steve, as stated somewhere upthread: from the first part 
of the prophecy, there is no way to tell it's about a baby. The one 
approaches may mean that an adult wizard is getting closer to his 
attack on LV. It could have meant a grown man with a July birthday 
whose parents had defied LV. LV had been around long enough for that.

So that Snape would not have a strong reason to expect it was about a 
young woman and her child. He was a DE and should have been held 
accountable for his actions. Which I think he was by DD.

My timeline may be off, but I think it's significant that Regulus and 
Severus came to a parting of the DE way at about the same time. We 
also have Sirius's statement that in the beginning, the WW didn't 
understand what LV was up to.

But, here's my real concern, did DD know that Snape was a DE that day 
when Snape overheard the prophecy? If he did, why did he let him go? 
Surely DD knew Snape would go straight to LV. If he didn't know, why 
didn't DD take some action just to keep the prophecy a secret in 
general?
