If the Department of Justice got its collective knickers in a twist over Fox News' James Rosen's reporting on North Korea, imagine the projectile sweat flooding Pennsylvania Avenue over this disclosure.
I have no idea what patterns of cell phone behavior the massive NSA computers have been programmed to detect and flag, but I'm pretty sure that flirting with the person in the next cube is not it. If it is then, to quote Roy Scheider as Chief Martin Brody in 1975's Jaws, "We're gonna need a bigger boat."
I have always assumed that any of my cell calls that included an overseas connection were being tagged by the NSA but, as my typical call involves trying to remember which country I'm going to (if I'm in the U.S.) or, how I'm getting home (if I'm overseas), I'm pretty sure the NSA has not tried to detect a secret Enigma cipher buried deep in Delta flight numbers and airport identifiers.
As far as I'm concerned, President Obama and the White House staff can spend all day and all night every day and every night looking at whom I'm calling and who's calling me - enjoy.
