I got into a lengthy argument with a fellow Albion fan on Twitter about this. My position remains the same - he knew exactly what he was doing and is nothing more than a cold-blooded murderer. For all those saying "You don't know what it's like out there," "You would have done the same," "It's war," bollocks to that. You don't execute unarmed, defenceless people lying on the floor in front of you, even in war. I can guarantee I would NOT have done what he did. He's a murderer and deserves his punishment, not public sympathy.
And the Taliban would have acted differently of course? Dream on.
