Potioncat:
I just realized your point was that Snape isn't working on a life 
debt obligation, he's protecting Harry out of general sense of 
duty.  Actually, that makes it even more noble (Did you intend that?)
Do I recall that you don't agree with DD's statement about the Life 
Debt?  I may have to find time to look into that...it is the sort of 
dis-information DD might hand out.

Although I said myself, I don't think Chief of Security is part of 
Snape's job.  It might be.  He seems to be the one who is most 
concerned by it.  Whether it's his nature or his responsibility, I 
couldn't say.
