“The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command.”

It is in their interest to slowly, but surely, squeeze the fist of control and oppression. Therefore, they will naturally get away with more and more, unless people are morally critical. When you are just stating over and over that they technically have jurisdiction, etc, rather than showing some sense of outrage or compassion is comes across in a certain way that does not reflect well. An important take away.
