Then the question is who is doing the "supposing"? I'd say if every government I've ever seen or heard of routinely engages in suppression of opposition, I'm going to suppose that the next government I encounter will as well. It's not like these are random government employees doing the suppression unprompted: they are in roles expressly intended to suppress opposition.
