Secret-Keeper Conundrum

[Sister Mary Lunatic]

No: HPFGUIDX 6142

If witches or wizards can hide their existence by the use of a Secret
Keeper, then theoretically, if the Secret Keeper died, that witch or wizard
could be permanently "invisible" to everyone.  Interesting thought...
Suppose you planned to commit a major crime, and convinced one of your
flunkeys to be your secret keeper.  All you'd have to do is kill the
secret-keeper and the law couldn't find you to arrest you.  Sirius could get
Harry to be his Secret Keeper, and never have to worry about being captured
by Dementors or the Ministry of Magic, since Harry would never tell.

This is assuming that the Secret Keeper spell works against everyone.  I
would assume it did, since if you had a "selective" spell that hid you from
one specific person or group, it wouldn't be totally safe because of the
presence of possible traitors.  For instance, if the Potters had set their
spell to work only against Voldemort, then all Voldemort would have had to
do is put a friend of the Potters under an Imperius Curse, to find the
hidden Potters and kill them.  Voldemort would never have to worry about not
being able to see them himself.

This is why I don't think that anyone is Harry's "Secret Keeper" -- if Harry
was truly hidden while he was at the Dursleys, then NO ONE should have been
able to discover his location.  But we've seen that even Lucius Malfoy's
house elf was able to find Harry and apparate into his bedroom at the
Dursleys.  The Weasleys drove up to Harry's bedroom window in CoS.
Something else is protecting Harry during his time away from Hogwarts. It
will be interesting to find out what it is...

Does that make sense?
