This is such a sad case. For the Afghans and for the soldier's family and so on. But this case rather proves our point...the soldiers in question (currently just one) are being made to pay legally.one has lost his family, his future, his freedom. This tells you that they aren't being treated as all heroes and how the UK is at least trying to obey the GC.
My current nearest hospital is regularly in the news for it's failings and the deaths in maternity and for old people. Does that mean all people there are criminals? No. Does it mean all nurses and doctors are criminals? No.
This case shows that one soldier was a criminal, possibly three. It doesn't say ANYTHING about the criminality of the rest of the armed forces.
