I'd say it is a bit more nuanced than that.
If I see you commit a crime than I know you are guilty even in the eyes of the law you are innocent until proven guilty.
Similarly if I don't see you, I am willing to give you the benefit of the doubt until proven otherwise and thus believe in the rule of law.
Anyone, in my opinion, who 100% believes in innocent until proven guilty is living in a fantasy land because there are enough cases/instances out there where the probability of guilt is 100% or as close as can be.
