House Elves and Unforgivable Curses

[Dave Hardenbrook]

I've missed a few days of the digest, so forgive me if this has already
been asked... But, in regard to the scene where Lucius tries to AK
Harry, aside from the apparent stupidity of Lucius risking his
"respectable image" by murdering Harry right under Dumbledore's nose,
I'm wondering -- Is this meant to be a clue?  Is Jo trying to hint to us
the extreme power of House Elves?  Is it even possible that... House Elves
can *block* Avada Kedavra??!
