Juror #8:
It's always difficult to keep personal prejudice out of a thing like this. And wherever you run into it, prejudice always obscures the truth. I don't really know what the truth is. I don't suppose anybody will ever really know. Nine of us now seem to feel that the defendant is innocent, but we're just gambling on probabilities - we may be wrong. We may be trying to let a guilty man go free, I don't know. Nobody really can. But we have a reasonable doubt, and that's something that's very valuable in our system. No jury can declare a man guilty unless it's sure.
