UMMMMMM You do not need to be a good actor ,just to see your life flash past you ,will surely make your acting abilities seem Oscar worthy ,I had a friend who wanted to leave the RAF many years ago and so he pretended to be mad,18 months later he was discharged. There is a very sad end to this story a few years later he hung himself from the hallway stairs so really there is no easy way out ,I think he is guilty and the TV programme made me feel sure, either way I think he is between Hell and High-water he could end up making himself mad and might face the prospect of being detained under the mental health act .
