I hope that Pamela's decision will arouse the interest, or attention, or outrage, of a few more people, who will in turn talk and write and advocate to get more people involved. Groklaw was a great resource; citizens will care that it's gone. (The government and its minions won't.)
Pamela's choice will likely be met with the usual arguments: the government doesn't care about your emails. If you have nothing to hide you have nothing to worry about. This is about protecting us from terrorist attacks, not about snooping into Americans' communications. Don't you remember 9/11?
I tire of responding to those. Let me offer one response that applies to all of them: I don't trust my government, I don't trust the people who work for my government, and I believe that the evidence suggests that it's irrational to offer such trust.
