This is a rambling stream of non-sequiturs and misleading statements. A key pull quote is "The NSA is not a law enforcement agency."

So? From the motto "We track 'em, you whack 'em" to parallel construction, we already know that's not a meaningful distinction. Then, ramble ramble ramble... we come to how North Korea is sufficient justification for a Cold War era budget for snooping. What?

Is this the best an NSA analyst can come up with? TL;DR: Claims of good intentions, feigned boredom about your emails (unless some software flags them), North Korea, and "we're not the cops?" This is very very weak.
