> Wikileaks has done tireless work in this field and has largely been correct about its claims and the authenticity of its documents
I believe what people don't trust is their motivation. I've seen people argue that motivation doesn't matter; facts are facts. That's incorrect, as anyone who has listened to a skilled dissembler state facts leading to a conclusion at odds with reality knows.
There are other problems, including suspicion that it may be true that WL may be leaking exactly what they're given (modulo redaction and strategic withholding), what they're given may be tailored to the goals of those leaking. Assange's statements don't help dissipate that suspicion.
So in looking at their releases, you have to fact in not only their (Assange's) motivation, but that of the unknown people leaking documents.
Ain't intelligence analysis grand?
