While greatly respecting Rowling's work, I really think she has 
slipped up with the Ministry of Magic(MOM).  Why is it that everyone 
can simply apparate into the Ministry of Magic (which is very relaxed 
as far as security is concerned)and disapparate without any 
problems?  We know that they can do that even into the Department of 
Mysteries (why else would Dumbledore place a disapparating jinx on 
the dark wizards in the Death chamber?).  
Why was Harry needed to obtain the prophecy in the first place?  
Wouldn't it have been better for the recording to have been 
destroyed?  Another thing: if Voldermort was so concerned about 
people noticing him, why would he have his whole sqad break into the 
MOM and take out any threats to help Harry along?  Why not simply go 
in himself undercover via. polyjuice potion or whatnot and get it 
himself before disapparting?  He really went out of his way to get 
Harry which doesn't make anymore sense than all the rest of it.  But 
hey, that aside, I love the book!
