This is a really frustrating mindset. I'm a defense attorney, and I can tell you a fast Not Guilty verdict generally means the prosecutor had a shit case. Or there was a strong defense. It does not automatically mean someone was guilty and the jury made a mistake.
Either way, this is the United States of America and we have a long, proud history of civil rights including the right to trial by a jury of peers. A group of people sat and listened to every word of that trial and collectively agreed on that verdict. We were not in that group. These are the legal principles we have followed for hundreds of years.
If this was one of our players no one would make these comments.
