You didn't err, you lied. You made a claim and then stated your claim was supported by a specific book. When it turned out I had the book you tried to deflect and deflect away from your claim until you could no longer do so.
You are a known and proven liar, and you do not understand really, REALLY basic things about intelligence studies (such as the difference between classification and China's blanket banning of things it doesn't like) so why should anyone accept anything you have to say on these topics?
You don't understand basic science such as what welding is, so why should we accept your claims to understand metallurgical studies well enough to report on what they claim, or even how they function? I recall you so obviously failing to understand how metallurgical studies are conducted that you misunderstood Jay arguing that they found no evidence of explosives because such evidence would have been obvious as him claiming they should have looked for explosives. To make it even more laughable, you have claimed, repeatedly, to be a scientist when it is so obvious you are no such thing. My 8 year old niece understands science better than you do.
You don't understand security and intelligence studies, so why should we take your claims as to how secret operations are conducted even remotely seriously? Your idea of spycraft appears to be based more on terrible potboiler thriller novels and the movies than real life.
The problem is not only that you're so far out of your depth you don't even understand enough to understand you're wrong, the problem is when confronted with people who do know what they are talking about you assume that we are all at your own level of understanding and whine that we can't possibly be correct because we disagree with you. You act as though you think that you have attained the highest level of knowledge available and that anyone who claims to understand these topics more than you is a liar.
The problem is we aren't liars. You just won't accept being wrong, to the point where you are still deleting posts in order to make this less embarrassing for you without even realising that ship has sailed.
You don't know what you are talking about, your sources are either delusional lunatics like Bjorkman, are working from incomplete information or simply do not say what you claim they say, and you've been so thoroughly shown as an incompetent arguer that no one reading this trainwreck of a thread could possibly conclude that you have a point.
