You obviously have never been shot before, loss of blood may have another injury we can't see.
I have actually been wounded on duty, so I find your what is crass assumption quite offensive. Tours of Northern Ireland, the Balkans and the First Gulf War.
When you ASSUME you make an *** out of U not ME
It was a question to W Britains for info?
Why are you also assuming he has been shot?
Blood loss, if you actually take even a minute to look there is very little blood on his bandage or uniform, plus the wound does appear to be at the elbow. Therefore could you bend your arm and grip hands! Unless you are a superhero!
