Looking at it from my point of view, as someone who has schizoaffective disorder, I have been afraid of the government for a long time.

I think it is because you hear and see about how governments can find out anything about people and spy on people. The thought stays with us, subconsciously, and comes out in paranoia.

I know for me, I started getting paranoid about being spied on after reading a couple political books (Bob woodward, Mark crispin, Noam Chomsky, etc) and started having to close blinds all the time, thought people were following me, etc. I still struggle with it sometimes, but I've realized how irrational it is.
