Dead Marine's father ordered to pay protesters' legal costs

As long as he hides behind diplomatic immunity, he cant be tried. He is a sovereign dignitary of an independent state. The guilt that he bares is not equatable to a crimnal charge, so your attempt to make the comparison fails. He is guilty of the coverup by the sheer fact that there ARE abuse victims, and that there ARE documents uncovered within the church that instruct bishops to cover up pedophile priests, and not to cooperate with investigative agencies of law enforcement.

Nice try, but you still failed.
