I can only speak from my perspective. The only people I see saying "the government would never torture" are those with a strong patriotic streak and desire to put tribal affiliation beyond humanitarian concerns.
And I don't think that 4chan or reddit really correspond with society as a whole, at least this side of the duck pond.
Now go ask the same question on r/politics (which is prominently made of up leftists) and you will probably be called a conspiracy theorist and no one will converse with you.
I think the real world is the opposite of your world-view.
