OOP: Blood Protection or No Protection

[pickle_jimmy]

No: HPFGUIDX 66315

1) Sorry if this had been done before (I've been busy for a week and 
missed a huge bunch of posts)

2) Is the OOP FAQ (which was a brilliant reader's digest version of 
the discussion till then) being added to as more topics come to light 
and have a general concensus answer?

3) Now for my question:

How much protection does Privett Drive offer Harry? No-one seems 
concerned for his safety while he is actually *in* the house, but 
extreme measures are taken while he isnt (eg the fact that he 
needed "eight or nine" wizards to escort him to Grimmauld Place).

He is just round the corner from Privett Drive when he is attacked by 
dementors, Mrs Figg has to get him back inside the house.

After the attack, Mr Weasley & Sirius are only concerned with him 
staying in the house.
 
Dumbledore is having him followed where ever he goes - whether at 
home or at hogwarts (he is followed on his trip to hogsmead)

So, obviously the house is safe, and seemingly outside the house 
isn't safe.

So what's the big deal about him calling Privett Drive home. He's 
only there during summer holidays - he might just as well have been 
at Grimmauld Place with Sirius - wouldn't that be *just as safe*. 

If this blood thing runs deeper than protection inside the house, why 
all the other precautions? If Harry is still in danger of attack what 
is the good of the protection? It's no use if it only protects him 
against Voldemort - Voldemort missed the end of the prophecy, so 
doesn't know it is him that is destined to kill Harry - he could send 
dementors himself to finish Harry at Privett Drive.
