When anyone starts to say he was unarmed and it was wrong I think about the innocents in the Twin Towers and on the tubes/bus in London - they were unarmed too.

You go around blowing people up then don't expect when justice comes calling that it's coming with a cup of tea and a blanket. If there was intel to be gained then yes he should have been taken alive if not then to me a double tap to the head was quicker and more humane than he deserved - period.
