People! Just because Knutsen bullied people back in high school doesn't NECESSARILY mean he's capable of killing a child. Some people grow up and change for the better, maybe not statistically, but it does happen. Never assume someone is guilty until it has been proven. There has been some compelling evidence that the accusation could be wrong. Apparently eleven jurors agreed.
No not everyone changes sorry. My ex husband was one of those guys that bullied people in school and would fight people smaller then him. Mind you know he does have short man syndrome as he got older and out of high school he stopped fighting men and started hitting women. It made him feel more like a man. He has been in and out of jail and is now on his 4th marriage. So no not everyone changes. If a person is doing that in high school they have a deep underlining problem to begin with.
