Double standards & the quick buck
The Sgt Blackman should not have shot the guy however the situation that Sgt Blackman and his unit found them selfs in was such that murder is not an appropriate charge, to put it simply you can't impose the same rules for a battlefield as you can for the streets of London.
Those who try to impose the same standards are usually the lawyers who stand to make huge amounts of money from the leagal aid system, some of these lawyers have known for years that the cases they pursued were based on very poor evidence and had little chance of success but persue than they did at great cost to the public purse.
However to me the the pursue of these cases in the face the lack of evidence is a crime on two counts, first those who found them selfs wrongly accused had the case hanging over them day in day out for years while they should have been getting on with their lives and forgetting the horrors of war and secondly a lawyer who continues a case that he knows is far from sound is stealing from the leagal aid budget.
I understand that the govenment is looking into some of these cases to see if they can recover some of the leagal aid money that was taken, the govenment should also look at taking leagal action against some of these lawyers for the mental anguish that they imposed for years on servicemen who innocence lawyers had become fully aware of but continued the case dispite the evidence ( or lack of ).
