It's funny how much we love freedom, but we (most of us) could care less about the government tapping our phone lines, or knowing what we look at on the internet. As a citizen with nothing nefarious to hide, we're not really concerned.
Guess that's what happens when you have very little to hide; and they've been doing it for so long that if we haven't raised flags yet then what's to worry about. They've been tapping phone lines almost since the invention of phones - research Senator McCarthy, President Truman and "Red Scare"...(you might even be able to find info on how Walt Disney was part of the fun) They started tapping phone lines almost less than 75 years after phones were invented.
Do you think they're really interested about how many cat memes you look up, or Someecard images, or that picture of you drinking half naked at your buddy's house, the Tweets about how you're horny, your Facebook status about how much you love your husband (and the subsequent Tweet about what an asshole he is) or your tit/dick pics? Probably not what they're looking for.
But, maybe if you're planning on overthrowing the government, or blowing some shit up...maybe then you don't want them to read about that.
Now, we could personally care less about the government trying to "protect" us from terrorists; but we'd wager that a lot of the people all freaked out about the government using surveillance techniques on it's citizens to try to prevent terrorism (allegedly) are the same who are absolutely outraged that terrorist attacks happen.
How do you want the government to try to prevent terrorist attacks like the Boston Marathon Bombing...Ouija Boards, prayer, psychics...magic?
Maybe...you know...just fucking pay attention all the time, not just when you want to be outraged by something you think is the fault of the political party, that's in office, that you hate.
