I don't know why this post is getting quoted so many times; it revolves entirely around a faulty assumption, namely that justice is perfectly served under the law, and that questioning the application of the law is itself irrational. I shouldn't have to explain why this is wrong.
People are not angry that Zimmerman did something illegal and got away with it. People are angry that Zimmerman did something that should by any reasonable standard be illegal and got away with it. If due to the absurdities of Florida state criminal law, a weak prosecution, and an unfortunate lack of evidence from one party involved, Zimmerman was declared not guilty despite his undisputed and entirely negligent role in creating the circumstances that led to the shooting of an unarmed person, that just proves that the self-defense laws in Florida are severely flawed and the justice system broken. Of course, this is by no means the first or only case that proves that, but it is the latest and one of the most tragic.
The justice system has not revealed some infallible and unimpeachable truth about objective reality here. It would be idiotic to say that the verdict actually vindicates or absolves Zimmerman in any but a strict legal, formal sense. It's only revealed that six people who don't bother to pay attention to the news were sufficiently swayed by a high-powered legal team and a horribly deficient prosecution not to convict someone under a precisely worded statute. Is this a victory for following the absolute letter of the law? Probably. Is this is a victory for anyone considering the ethics of what happened and what it means for our broader society? Absolutely not.
I was just about to quote that post and write the same response. Well said. The justice system is supposed to be a formal representation of our collective sense of fairness. The verdict of this case only served "justice" in the legal sense that it abode by the rules of the American justice system. "Justice" as an extension of the human sense of fairness was not served. It's not fair that Zimmerman created a bad situation and ended it in the worst way possible and was not punished for it.
The lack of punishment for Zimmerman is a symptom of a flawed justice system, not proof that justice prevails over vengeance. This verdict demonstrates that, as long as there is a lack of witnesses and you make a case for "self-defense" when the trial comes, you can get away with killing someone. That's a chilling thought that demands a re-assessment of the system.
