"What's your problem?"
"I've done a terrible thing. A bloke is dead because I was mucking about. I'm so sorry for what I've done. This bloke was on the platform. I'd had a good drink. I was taking the piss out of him. I'd pretend to throw a punch at him, but made no contact. He did not respond to this. I'd walked down onto the platform. A few minutes later he appeared on the platform. I thought he was with a female. I started to show off again. I said to him, 'What's your problem?' I walked around him. He looked at me. I said, 'What's your problem?' I then aimed a punch at him with my right fist. I did not use my full force, it was more like a jab. I think he saw it coming because he swayed backwards, so I just clipped. He seemed to lose his balance and fell backwards. I did not see him hit his head on anything. I walked round him. I could not understand why he'd not got up. I ran way."
"I have been working with Callum for almost nine months. During this time I have seen a noticeable change in him. He has matured and is keen to gain qualifications in custody. There was an incident about six months ago where another young person was inciting [him] to fight. [He] acted in a mature way and instead of reacting spoke to unit staff who were able to deal with the situation. I believe this demonstrates a positive change in Callum."
"To that we would simply add, having considered the very many authorities which we have now considered, that it is in truth not realistic to treat what is described as one-punch manslaughter as comprising a single identical set of circumstances. Cases involving death which results from a single blow vary greatly in their seriousness. That fact is reflected in the very wide range of sentences which have been imposed by different courts dealing with them. 11. We should perhaps add that a lengthy debate about individual features arising in each of the different reported cases rarely assists. We cannot approach the decision which has to be made, nor can sentencing judges, on the basis of drawing up a list of credit and debit points in each of those cases, so as to see which of them are reflected in the instant case. Perhaps all that we need finally say is that in truth we are dealing with an unintended death which resulted from unnecessary violence."
"What has struck us, as we have considered this case ... is that this kind of unnecessary violence, in residential areas, creates great, and justified, and increasing public concern."
