With any right there are associated responsibilities and restrictions. The 2nd Amendment guarantees the right to bear arms — well, not if you are a convicted felon or criminally insane. The 1st Amendment prohibits abridging the freedom of the press. I assume that does not include publishing my Social Security number or my IRA account number and password.
The Associated Press' reporting of the details of a foiled terrorist plot to bring down an aircraft is not holding the government accountable. Instead, it endangers the CIA operatives in Yemen who stopped the bombing. As a reader, I would not feel victimized if I didn't know this.
When the media accept their responsibility not to report leaked classified information, there will be no need for the government to seize the records of news agencies.
