For many years the government has been monitoring radio waves of their adversaries. Recently, they have figured out how to monitor your mind.
Using your brainwaves as if they were low frequency radio waves, they can read your mind. The biggest challenge was decrypting the waves. Using a base key, they can. This is accomplished by sending a control pattern to your mind then registering it. Using television, what you hear is used as the decryption key.
Once they have they key, they use cell phone like handhelds to record and process the info.
