That's not core to me. The litigation system is highly cultural, can be a village assembly before the eldest, a full judiciary system as we have in the West, can be based on Roman law or jurisprudence. Presumption of guilt is just another way.
You can't shorten it like that. It's a complex litigation system were we westerners, when applying our own interpretation grid, see a presumption of guilt.
For the core human values, a good example is the case of a little girl running dangerously near a well, any human except some psychopath will jump on their feet and save her. Here we all share something that can be qualified as universal.

You're arguing that "presumption of guilt" is somehow contextually relative. It's not. If 99% of "trials" result in a conviction, there's an unequivocal presumption of guilt.
