Right, so now there's no way to verify his claims. Accuse the Tech companies of not being truthful when they say that don't allow the NSA arbitrary access, but then offer no details that would actually substantiate the interpretation you made of the slides. How very convenient. And how would divulging the NSA's program not harm their collection, but divulging the details would? If I'm the Germans and using Enigma, knowing that it was cracked, but not how it was cracked, would still get me to change my behavior. If I'm Bin Laden, I don't have to know the technical details of how my satellite phone was tracked, just that they were doing it. The harm has already been done, and now the harm to these tech companies is being continued with daily innuendo and no hard evidence. How much longer can this go on? Can the Guardian just keep going on for months making allegations without hard evidence?
