How are we to wind it down, or even know that we want to wind it down, if we don't know what it does? The reaction to all of this over-the-top foreign spying stuff is as loud as it is precisely because most people were not aware of its extent, regardless of the stated mission of the NSA. The NSA grew so large and powerful because its projects were secret and thus largely shielded from public review. In that light, the secrecy is a lot more than an operational detail; it's a deception directed at the American people in order to pursue unpopular security policy. Note, for example, that even the NSA's budget is classified. They've built something very big, and they were only allowed to do it by keeping it in the dark.
To put that another way, if it really is merely the NSA's stated mission and revealing its secrets is mere sabotage, why is it scandalous that they tapped Angela Merkel's phone? Why is it outrageous that they're spying on Google's intra-datacenter communications? Why is tracking the world's cell phone locations an embarrassing thing to have done? Because if we'd been asked, we wouldn't have let them do it. But we weren't asked, because secrets.
Thus, I think that revealing the extent of NSA spying, including all of the foreign stuff, falls in this bucket:
> Revealing that an entity is doing things it should not be doing so the correct oversight can be put in place.
In my view, our government doesn't have a fundamental right to secrecy. We provisionally granted it the privilege of keeping some things secret from us (remember, we're The People) because we felt it was in a good position to make the tradeoffs required there. It has systematically abused that privilege and now it's lost its claim to it.
Sabotage: I will secretly undermine your operations and try not to get caught. My sabotage is operational- it is most effective when undiscovered.
Civil disobedience: I will publicly defy your rules with every intention of being apprehended. My defiance is political- it achieves nothing by itself, and must be public.
Yes, both involve breaking rules, but that is where the similarities end.
The point behind civil disobedience is to publicly demonstrate the unjustness of the law, not fight it head-on. Remember when those nonviolent University students a little while ago got pepper-sprayed? Much, much better press for them and their cause than "students start brawl with police".
Some people believe civil disobedience doesn't have to be nonviolent, but most people agree on nonviolence and all the famous examples of civil disobedience were nonviolent (Rosa Parks, Thoreau, Gandhi, etc)
I said nothing about violence - in fact, your comment is the first on this page to mention violence - so I don't really understand where you're coming from.
Whistleblowing: Revealing that an entity is doing things it should not be doing so the correct oversight can be put in place.
Sabatoge: Deliberately destroying the capabilities of an organization by means of deception and rule-breaking.
I am 100% for the former. I am against the latter, even when I agree with the philosophy behind the actions.
