Really? I didn't realize this. That's encouraging. I thought that it was a very specific task: to evaluate the evidence within the framework of the law in question.

That's what the judge will instruct the jurors to do, but judges have little to no legal authority to coerce jurors to do so. The jurors have live with consequences of their choices for the rest of their lives and "I was just following orders" may not be good enough to sleep at night. morality >> legality fija.org has a lot of good info on this subject.
