http://cryptome.org/ is a reliable resource is it? Because it looks like a conspiracy website.
They intentionally make no judgement on the things they publish.
It is a note of importance however, to realise cryptome - in the case of most of these source documents - are serving as a host rather than linking to the original (guardian/WAPO/firstlook/der speigel etc.) websites, probably as much for posterity as for convenience.
I see little reason to question the veracity of the info provided on this site.
