Hell, I'm even in favor of some SIGINT, as long as we are talking simple node-to-node analysis. But that's not what happened. What happened was a vaccum cleaner. They're sucking up every piece of meta-data they can get their hands on. And it's not because of some cost-benefit equation that the public was shown. It's simply because they can.
As a patriot, I feel that the only patriotic thing to do for all other patriots is to come out, rally and support Snowden. The government has stepped over the line here, and we all need to clearly let them know that this needs to be fixed.
And no, this case is not the same as Manning. Snowden saw one thing that he was willing to take the penalty for. He released data on one thing. Now, as the natural legislative body of the state, the people can make a choice whether to support him or not based on this one issue. I can support that kind of behavior. Manning betrayed his country by releasing everything he could get his hands on. He is truly an enemy of the system itself. Different thing entirely.
