The last two people in Eugene that got lesser plea deals testified against the guy who instigated the multiple bank robberies, kidnapping and death of the man who was killed by shoving an arrow into his ear canal and into his brain, although he  was also strangled with a chain at the same time.

He was sentenced to death, the guy shoving the arrow got life in prison and the girl got a lesser sentence.  

Works for me.

And it worked for the jury who didn't come in with their own agenda as yo would if you were called as a juror.
