I was in the British police force for several years and was so glad I never had to go to an infants school, bend down to chat to the kids, knowing that I had a gun in my pocket. There are not many english bobbies that would want to be armed..."stop or I'll shout stop again" springs to mind, but that's just the way it is. Tony Martin is a difficult case, the law says to defend yourself but only til the assailant retreats and then no more. I'm not saying that this is necessarily right, but the line has to be drawn somewhere. Tony Martin was obviously frightened when he heard movement in the house - who wouldn't be, but was he right to take a gun and shoot that young man? Perhaps nobody knows except Tony Martins conscience....
