I disagree with the court system being the problem. If you want to do away with the right to trial by jury and our constitutional rights, feel free to say so.
The court system indicted this officer and brought him to trial for murder. The state tried to prove that he killed a man without justification for self-defense. That is the system. Not liking the verdict is not an indictment of the system unless you want to give up your rights as I said before.
The officer has rights also and looks like he had a very good attorney.
