>>I was just  thinking were all those protections really necessary 
? I am mean Fluffy the Three headed dog, The Giant Chess set, 
The Flying Keys, The Potions  riddle and the Troll and finally the 
Mirror Erised. Why did Dumbledore go through all that to protect 
the stone. Wouldn't the  Fidelius Charm be a much better form of 
protection with Dumbledore  himself being secret ?

JR:
 
>> I always wondered why Dumbledore had all those protections 
up, but  for a different reason.  If the stone would only become 
available to  a person who wanted to find it but not use it, then 
Quirrel would  never have been able to get it anyway so what was 
the use of all the  tests.  <<

As Dumbledore says, the mirror has caught many who were 
blind to its dangers. Only someone who had a strong desire to 
find the Stone would try to get past the protections, and if they 
hadn't been warned they would then find themselves captivated 
by the Mirror.

 As long as he retains his vapor form, Voldemort cannot die, and 
therefore will outlast the  Secret Keeper. If the Secret Keeper 
uses the Stone, that risks revealing its whereabouts.

JR:
Similarly I have a probelm with the prophecy in OOP.  If 
 Dumbledore knew it already and they didn't want Voldemort to 
get it  than instead of guarding it, they should have just sent 
someone in there to knock it off the wall with a spell and break it 
and then  they would never have to worry about Voldemort getting 
it.<<

The same argument applies to the Stone. But Dumbledore 
couldn't destroy it until he got Flamel's permission because it 
didn't belong to him. The Prophecy Orb belongs to the Ministry.
