Whilst I agree with this verdict - I do think there is a danger of turning George Floyd into a saint.
I don't think this is what anyone wants. However, it did take this man to lose his life for change to begin, so he will be remembered. What we all should want is justice for all.
We also need to bear in mind that our policing is policing by consent - the common consent of the public. In the US policing has a strong relationship between politics and the police. We have a movement in the politics of this country towards White Supremacy and also, in my opinion, English White Supremacy. We need to ensure that groups supporting these views do not gain power if we feel that the policing that led to the death of George Floyd - an example of what happens daily - is not to come here.
This is the first time a white policeman killing a black man in this state has been found guilty of murder. Before this the only time a member of the police has been found guilty of killing a member of the public it was a black policeman and a (very wealthy) white woman. In the US the law gives "qualified immunity" to law officers and in many States, the force investigates its officers.
Hopefully, all countries can learn from one another.
