In the cartoon, there are two men. The man in black who looked like a spy in movies held a suitcase with the words “NSA” on it represented the National Security Agency (NSA), and it gives a background to the cartoon that it was happened in America. So, the other man who dressed like a construction worker can be interpreted as representing the general public of the America.
From the dialogue of the construction worker, it can be found that he did not care much about his privacy as he thought he had nothing to hide. But then, when he tried to tell the man who is representing NSA about his daily conversation with his friend, he found that he had already know it.
This editorial cartoon aimed at raising the awareness of the American people in protecting their own privacy from the government. The author was trying to show the audiences how horrible and serious it will be if the person who is beside you may know every single piece of details of your life, even the casual conversations with friends. It also showed the negative attitude of the author towards the intrusion of personal privacy of the US government. Therefore, the author is trying to tell the audiences that even there is nothing to hide, it is still important and they still have the right to keep their personal data and privacy to their own.
