Well, I hope he is found guilty.
However, I think this sort of vicious behaviour is not an isolated incident and, in my view, suggests an accepted culture of violence, threats and intimidation in law enforcement. As with the Rodney King scandal many years ago, this case has been particularly highlighted because of the filmed footage, which was appalling to see.
It is important that this man faces justice, but just putting one man away will not stop this sort of brutality and discrimination. I believe that in many states in the US the recruitment and training of police officers is far from rigorous and it seems to me that the whole system of recruitment and training needs to be completely overhauled.
