Thought Crime 1.0

Scientists have successfully extrated images directly from someone's brain.  Eventually, they hope to be able to watch people's dreams.  Orwell wrote about thought crime under the assumption that one's mind would never be able to be read; this potentially is even scarier than the thought crime described in 1984.  Potentially, the thoughts in your head could be subject to the whimsical world of government surveillance.  If you think this is an impossibility, or that it would never happen, perhaps you need to grab yourself a copy of 1984 and ponder the implications.  Granted, I've often been accused of being a hypochondriac and a little dooms-dayish, but am I the only one who foresees the government using this under the guise of national defense?
