I wouldn't go that far. I'd say arguments from emotion have no place within a jury's deliberations. Women TEND to make these arguments more than men, in my experience.
Emotion has a place in the world -- it would be a dull world without it. And certainly jurors feel emotions when they listen to testimony. But a jury needs to consider evidence and the law, period. The voir dire process, in theory, should winnow these people out, but I don't have the highest confidence in voir dire. Look how well that worked for O.J.
I couldn't believe that any person in their right mind truly had a REASONABLE doubt that O.J. was guilty. I was stunned at the verdict, as I'm sure many Freepers were. Maybe that's why I read Ann Rule true crime books. She picks cases where the bad guy gets caught and punished, and where the police and prosecutors are the GOOD guys. I can't wait for her book on the Green River Killer. It probably won't come out for a year or two, however.
