I read an article that talked about how our legal system and criminal trials are not just a game. Unfortunately for some litigants, it is. The article talked about a Florida Supreme court case, Johnson v. State, 44 So.3d 51 (Fla.2010), where the court spoke strongly against prosecutorial misconduct and that there should be no room for it in our American legal system, no matter how disturbing a crime may be or how unsympathetic a defendant is. They go on to talk about how the same principles of law apply equally to cases that have stirred passionate public outcry as to those that have not. "..In our system of justice, ends do not justify means. Rather, experience teaches that the means become the end and that the irregular and untruthful arguments lead to unreliable results. Lawlessness by a defendant never justifies lawless conduct at trial."
I don't think people realize this happens more often that one would think or would hope for. In this case, the Supreme Court caught it, but how often do these incidents go unchallenged and uncorrected.
