Before everyone feels the need to email me about this, let me make clear that I think Andrea Yates is guilty. My problem is with the law. I think she is guilty, but I also think she is clearly INSANE. Her guilt should be duly noted, and then she should spend the rest of her life in a mental facility. I do not think a lifetime in jail/the death penalty or freedom via insanity defense are the only options that should be available.
As I stated at Protein Wisdom, I think it is as morally indefensible to execute an insane individual as it is to execute a mentally reatrded individual.
