Would JKR lie to protect her story?

I was reviewing interviews with JKR earlier today, and wondered, if 
someone asked her a question ~ that gave her no choice ~ would she 
lie to keep the story from being revealed?

We are all so hungry for tidbits of information, that naturally we 
want to accept what Ms. Rowling says as cannon ~ but as she has 
said, she will be able to have a frank conversation after Book 7 is 
published ~ and won't have one before.  She simply can't ~ if 
someone gets too close to the truth ~ and even her avoidance of the 
subject will let the plot slip ~ I believe she would have to lie to 
protect the entire septology's secrecy.

She once said that no one has come close to guessing what she has in 
store.  But what if someone did?  Even if she were to answer "No 
Comment", "You'll find out", or "I can't answer that" to some 
questions ~ it inadvertently lends credibility to the theory 
presented.  I believe that she must therefore answer "No" at times, 
even if the information might be true.  Don't get me wrong, I think 
she has a great time rewarding those of us who decipher running bit 
clues - but I have to think septology plot clues are different.  
Bottom line ~ she wants us to be entertained until the end, and I 
don't believe that she would allow one good question to ruin all of 
the suspense.  I think she would choose to fib instead.  

So, if that is indeed the case ~ can her responses be used to prove 
or disprove any theory, really?
