Can an unbiased person explain to me how this revelation is a threat to national security? Are terrorists going to stop saying, "Ok we blow up white house tonight!" over Skype or something? Are people just afraid of the bad publicity that goes along with spying on citizens and other nations? If that's the case, it's really sad: It's like a mother yelling at her children for speaking up about her once-secret abusive nature. I fail to see the danger or wrongdoing in this.
