He's dead! Is he?

OK so all the conspiracy theories I have come across and none of them take the logical view, why would US intelligence want to kill him off immediately? Wouldn't it be more prudent to assume that they "took him for questioning" or you could believe that he was too much if an embarrassment to a certain family and so was assassinated, but that would leave the big hole in the intelligence side, why didn't they keep him alive for questioning? He was "unarmed" why shoot him in the head, the leg would have been more effective.

Just a thought 

OK I am officially willing to return to work, I know it sounds like a disease but I want to go back to work and earn some cash, I would also like a pay rise, and a new car (nothing to do with the job) and a...... yes wish lists and more
