This appalling attack is more than a case study in sociopathic evil. It is also a case study in journalistic malpractice. Unless you tune in to the local Knoxville news, you are most likely hearing about this heinous crime for the first time — even though it took place last January. True, there are some 17,000 murders committed in the U.S. each year, but this double murder was clearly far more barbaric, far more monstrous than most.I spent six years in law enforcement and have seen my share of war-ravaged third-world nations, but the deliberate and abject inhumanity of this case, and what it says about our culture, certainly got my attention. Yet, this story has failed to attract the attention of the national media. Could it be because the two victims were white and the five defendants are black?
