So I think that the government thinks the Proles don't need Telescreens because they are innocent! Most people would think that because they make up 85% of the population that the thought police would want to see what they are doing and hear what they are saying. But the Proles are kind-of controlled by their own "stupidness" or ignorance! They also are given alcohol because the government thinks if you keep them drunk they are easier to control....so, they don't really need to have telescreens!!
