So responding to your fluff and nonsense with the actual documents from which you cherrypicked is considered "rhetoric" or "generally acting obnoxious"?
In your opening post, you interpreted the partial document to which you linked as, "the FBI has no record of any evidence associated with the four flights used in the terrorist attacks". This is incorrect.
I posted the complete documents to show that this is incorrect. If you bothered to read them, you would see that what the FBI has said is that it has no documents
responsive to the specific FOI request to which it replied. There is a vast difference between that and your interpretation.
I'd suggest that you read the documents instead of taking one sentence out of one document and making unsupported pronouncements on the matter as a whole. You can find them here:
