Well, as I pointed out in my blog post http://kirk.blogspot.com
today, George W. Bush is guilty of violating Title 18 United States Code, Section 113C a.k.a the federal torture act. The punishment for violation of the law is death. Reading it closely though, there are some catches. First, the death penalty applies only to torture that killed people (which has clearly occurred) and he would have had to be the one who actually did it. Telling other people to do it may or may not count. (We'll decide at the Tennis Court.)
In part C it states that "A person who conspires to commit an offense under this section shall be subject to the same penalties (other than the penalty of death) as the penalties prescribed for the offense, the commission of which was the object of the conspiracy."
So, conspiracy to commit torture is exempted from the death penalty. It is, however, punishable by a life sentence in jail.
