Morally I'm opposed to the death penalty, but the poll asked if it was "justice". If you go by the "eye for an eye" code that most of the world's justice system operates on, then yes it was just. If he were put in prison, I'm guessing that the Iraqis would want to hold him. And didn't some former government minister (indicted for much less serious crimes) just walk out of a prison guarded by Iraqis - twice?

Anyway I'm opposed to the death penalty on religious grounds but it was justice by the world's standards.
