Ah big brother. Personally, I believe that the government has a lot of things to worry about, and in the age of computers security is a convoluted and almost impossible task. I could see both sides of this. Yes it is incredibly intrusive for the government to be able to see everything we do with basically no real system in place to stop them, however, most people voluntarily give all of their information to mega corporations that only want to make a better AI to get their money and sell their information. If you are willing to part with your info so readily for the sake of posting pictures or messages online, then I think it is difficult to condemn the government for using it for the sake of national security.
