Erin, your subject seems interesting and challanging despite it is vague.
What does the "Big Brother" refer to? Is it the government of a country.
If it is, some country might change facts, harvest propaganda but we can not
generalize all the country in the world. If you are able to support with facts and
figures, then it is different story.
Citizens of most of the country have the constituational right to question their authority. If you link the
government propoganada , media censoring,and the peoples' valid question to the authority and their
results or finding related subject would be a good research, in my view.
