Why Darren Wilson will possibly not be charged.

Found this letter to the editor of the UK Guardian. The author expresses opinions held by RWNJ's who have never known the process of analytical thinking. Perhaps thinking itself is just a bit beyond his capabilities.

The grand jury is necessary to determine if there is probable cause to believe a crime has been committed. Adding up all the public statements of all the witnesses and the autopsy reports, I would say that, IMHO, Wilson did not break any law in the shooting of Brown.
Tasers have a range of 15 feet and require both needles to be embedded in order to work. Apparently, Wilson didn't have a Taser anyway.
It is much harder than you think to shoot someone in the leg. If you have your gun out, and an assailant gets to you, there is a good chance you'll be killed with your own gun unless you shoot him. Police are taught to fire at the center of mass (the torso) and to keep firing until the threat is down.
The US is not a Nazi state. If you want to change the law so that police aren't allowed to pursue felony suspects, you are perfectly free to approach your state legislators and try to sell them on that idea.
If you want to change the laws on self-defense, you can follow the above procedures.
If you don't want police to shoot people who attack them, you'll have to restrict job opportunities in the police forces to people who are professional boxers or football players."

The only law broken by Darren Wilson, according to competent witnesses, was "Thou Shalt Not Kill."
Wilson's life was under no threat at all. Will all HELL break loose in Ferguson if Wilson is not charged with murder? Gov. Jay Nixon thinks so.
