Whoare the though police and what is thoughtcrime?

THe thought police are the secret police of the Party. They are kind of like the SS of Nazi Germany. They look for people who might be thinking thoughts contrary to the Party's interests. They look for facial expressions, off handed remarks, a suggestive eye twitch....A thought crime is simply having a thought that the Party doesn't like. Penalties for thought-crime range from work camps, to torture, to death.
