It seems to me that the U.S. government will execute Moussaoui for being an Al-Qaeda member and a wannabe standby member of the 9/11 crew. Any rational actor would not behave the way Zacharias has these past years. Just contrast his behavior to that of Brain David Mitchell, who was found insane in Utah. And I am not the only one who thinks Moussaoui is crazy. [From the NY Times]
Dr. Xavier Amador testified about an encounter with Mr. Moussaoui last April in the holding cell of the courthouse in which the trial is taking place. He said Mr. Moussaoui repeatedly spat water on him and exhibited several classic symptoms of schizophrenia, including sudden shifts in the defendant's views accompanied by denials that he had only moments earlier held the opposite views.
Under questioning by Gerald T. Zerkin, one of the court-appointed defense lawyers, Dr. Amadeor picked apart Mr. Moussaoui's testimony last week in which he seemed to offer rational, if not plausible explanations for his odd behavior over the previous four years. For example, Mr. Moussaoui had regularly charged that his lawyers, whom he reviles, were part of a conspiracy to kill him.
I know people want revenge for 9/11, and the families deserve justice. But killing this man really isn't going to do it, because he did not do anything to further the 9/11 attack, didn't know about it, and was mentally incapable of doing so.
If you are so wacko that bin Laden doesn't think you are a good candidate for a suicide bombing, you have some serious issues, to say the least.
