Say there was a totalitarian regime that controlled 1 billion people. The GDP is ~$50,000 per capita.
This regime has nigh on total control over them, however, rebels are still considered a serious threat to their power.
If you were the newly appointed head of the Ministry of Safety and your job was to manage the myriad of intelligence sources the country had, (Cameras, texts, mail, etc.) what methods would generate the best results?
The Party will be grading you on these metrics:
+Quantity: The total number/% of people(surveiled?). This should be as close to 100% as possible.
+Quality: How often any particular person that is not under direct suspicion is watched (What sort of subversion could they be up to in the meantime?!)
+Cost: The lower the cost the better, although not at the expense of the other metrics($ cost per person).
Your class 8 dwelling awaits, comrade Minister.
