Thread too long for me to bother checking if someone has already said this but you don't need intent to kill to be done for murder in the UK.
Intention to cause serious harm (usually GBH) which then leads to death is enough. The main case on it is Vickers, a burglar who was interrupted by an elderly lady. He beat her up before running away and admitted that he attacked her but had no intention to kill her.
I'd have thought that under UK law you could try and argue that he did intend GBH and that it lead to death so try for a murder conviction, I'd usually say you'd never get a conviction in this type of situation but video is pretty damning. Whatever we think of racial tensions and police mistakes in this country (Stephen Lawrence and all that) we're just not in the same league of issues as the USA. As much as we do still have institutionalised racism it manifests itself in a much less violence manner and it feels like progress is made with each generation - I'm not sure the same can be said for America.
I think because a lot of cases are downgraded to manslaughter to ensure a conviction if the defendant pleads guilty, there is a general assumption that you have to be Dracula or Julius from Pulp Fiction to prove intent. If that was the case, bombers who gave a warning would always be able to claim 'I never intended to kill anyone'. But as we saw in the 70's and 80's during the Troubles, that was no defence from a murder charge if your bomb went off and the area hadn't been cleared and so forth. And don't forget, you can still get life in prison for manslaughter in the UK anyway.
