I have also on BBC news interviews seen black victims who have not felt the matter racist.

My own opinion (and I am white) is that the reasons for the delay were incompetence, stupidity, negligence, etc. but I don't (at least as yet) believe racism was the reason for the delay. That is not to say that I don't believe there are issues in all this that do involve racism. The underlying social conditions should raise very serious questions, and I suspect questions not just confined to NO.
