The defence seemed confused, didn't they? At one point, they argued that it was an accident, but then that P thought a burglar had got in. That doesn't add up. Apart from that, it was a lot to do with his state of mind, which is difficult to compute. I was surprised when the higher court ruled that he could not have feared for his life. Why not, if he thought a burglar was there and he is walking around on stumps?
