How many people do you have to kill to merit a death sentence according to the "Human Rights Watch"?
I'm sure they would support a death sentence for George W. Bush if he had an overdue parking ticket.
Apparently not all victims are created equal.
You have to be a pro-American, anti-abortion, red-blooded Conservative Republican in order for Human Rights Watch to support your execution. Typical liberal thinking.
Likewise IIRC, there was absolutely zero protest of the execution of Timothy McVeigh, from anybody right or left or ACLU or Amnesty International or etc etc ... everyone pretty much agreed that McVeigh had to go for his crime, and it was done quickly and without much press.
