Rather than debate direct access why doesn't the NSA release a video of what access they do have...
While it might be reasonable to not know who the NSA is searching for, it is reasonable for the public to be informed of what kinds of information the NSA could tap, and whether the public feels that is something the NSA should be doing.
Is that a serious question? NSA is never going to tell you exactly what access they have.
Look at what Google and Microsoft are doing; that's how we'll make progress, by having the NSA finally piss off the wrong kinds of companies (read: not telcos with enormous government-granted monopolies) who will move to force the government to allow them to say what's actually happening.
