vikingpower writes: There is new, quite hard material published by The Guardian on XKeyscore, a program permitting NSA analists to search pretty much everything a user does, types, searches or sends online. The Guardian has a slide show that is actually NSA training material for the XKeyscore program. It is now clear that NSA analysts require no prior authorization for searches. The article is partially based upon a further interview with Edward Snowden. Enjoy.
