If what happened to the director of the CIA wasn't a wakeup call to everyone, then they're going to stay asleep. The FBI cracked his gmail account with obviously no effort and without there being any evidence of an actual crime taking place. There was no legal support for what they did and yet they were able to get full access to not only his personal account, but to his mistress's. I may have read one article about the implications of this ability shown off by the FBI, but everyone else was too interested in the sex scandal to even notice.
And that was the FBI, which needs to at least appear to be following procedures and regulations when it wants to build a case for court. The NSA does not need to worry about oversight
