I would not want to be a juror on this.
It would be tough. I consider myself a straight shooter and place a high value on ethics and fairness.
This case would push those values to the limit.
Like you, I would take no part in convicted this man and going to prison. I don't think I could do it.
But at the same time, we are a nation of laws. This isn't 1880s Wild West. You can't just shoot someone because they punched you.
But this is Chicago. You put a couple anti-gun nut liberals on that jury and they will fry him.
