re: What percentage doubt would cause you to acquit?

For a trial where the defendant could get the death penalty, I'd have to be 100% convinced by evidence that wasn't circumstantial. There are so many cases that hinge on that circumstantial proof and juries have to make a judgment.

I would want to feel good about my personal judgment and if I didn't I would vote to acquit. There's no middle ground when you're judging someone and I sure wouldn't want to send someone to prison based on a feeling.
