This article by Nicholson Baker has some good data and facts in it. However, I believe to get published, he may have toned down a few truths. To take his softer approach to the intentions of these experiments he ignores the human condition and what angry, disgruntled, vengeful, hated filled, or out right evil people are capable of doing. Yes there are people involved in these experiments and studies that want to do good but the increasing numbers of labs and the numbers of people involved heightens the inevitable outcome that someone will get greedy, succumb to delusions of grandeur, or contemplate and act on a plan to harm people.
