I don't understand the fuss...
The Jap guy is a journalist: a real one (not the SPH propagandist slobs) who ventures into the warzone to gather news. Risk is inherent in his job and he knew it. Many journalists die while on the job.
The Jordanian pilot is an enemy combatant, they have every right to kill him, Geneva Conventions be damned.
So, ISIS are the bad guys now?
