Seriously, really, what if everyone on a US jury would be called a "judge"? Would they then not be "fellow citizens" anymore?
Fact is, they're not even called "judges" in Sweden either. It's hard to translate; it means something like "committee persons".
They are of course also our fellow citizens. They serve on more than one trial (but this is not their job), they're fewer than on a US jury, but the difference is one of terminology and numbers, not principle.
They're not there to convict the innocent any more than US jurors are there to convict the innocent. It boggles the mind that smart people toss around the idea that they can be.
