the man..I do live in England.
Murder must be premeditated. Throwing someone off a bridge is going to kill them. That is premeditated. Keeping a baseball bat by the side of your bed and banging a burglar on the head killing him could be seen as manslaughter, You could kill someone by simply having an arguement in the street with them, stressing them out, causing them to have a heart attack. That cant be murder.
I do hope and believe that these kids were tormenting and had no intention of causing death but that would be for the court to decide. If they knew he had a heart condition that caused the heart attack then they could be seen to be guilty of murder, otherwise I dont think you could even callit manslaughter.
What is sickening is the result of their torment, the agony that his family must now go through and the torment that these kids and their families must go through when they realise what they have done.
Martinbishop is right........we the adults are to blame.
