I was the jury foreman for a murder trial where a pistol was used.
The question of what we thought about firearms ownership, etc. never came up during jury selection.
There were, however, many questions about what we thought about "diminished capacity" posed by the defense.
The prosecutor asked numerous questions about the jury pool being victims of violent crime. He also dismissed anyone who had served on a murder trial previously.
When we were in the jury room, it became evident that the state was not able to prove murder. We settled on manslaughter. There were two that held out for outright acquittal and two who held out for murder in the first degree.
The other eight of us were in the manslaughter area. We had to convince the other four of the correctness of our ways.
The biggest bone of contention was the armed criminal action charge that was stacked on top of the murder charge. It seems, IIRC, that Missouri law automaticaly adds this to any crime committed with a weapon.
I believe that if we found the defendent guilty of killing his wife, we had to convict on the "armed criminal action" charge as well. The problem, for our jury, was that the punishment for this charge could be a longer sentence than the killing (manslaughter) itself.
The guys that held out for murder now used this charge to try and get the maximum sentence. It was during this time that the anti-gun bias of these guys showed up. They could not get over the fact that a firearm was used in the killing. To the rest of us the women was illegally killed and the method/weapon used to kill her was immaterial.
After some contentious debate we finally recommend some sentence to the judge. I don't know what the guy eventually recieved because he was sentenced several monthe later and the jury was not involved at that point.
PS I hope that I did not hijack this thread too much!
