As I mentioned in response to the NewStatesman article linked above, as an Islamist, Anwar al-Awlaki would not recognise US courts anyway, so why should victims of his hate concern themselves? Martyrdom through a touch of his own medicine would surely be his preference. Unlike the Kafir he despised so much he was mistaken in his beliefs so he will have his just reward, but not 70 virgins he might be expecting!
Now another headline as emerged, "Awlaki death unlikely to concern Arab world", emphasising how complicated these issues can be. If the Arab world will not miss him, why should we? He was a legitimate target whose poison was best neutralised.
