Mr Blair gave a speech in Cardiff yesterday regarding gun crime in the black community, here . As black person, I'm cynical about his motivation for this.
As far as I know, the black community have been denouncing what has been happening and there is a lot of community based work going on to address the problems and steer vulnerable youngsters (black, white, Asian) away from gangs and crime. I don't know anybody who is burying their head in the sand and pretending it is not going on.
He probably feels the need to appeal to Mr and Mrs Outrage who read the Daily Hate.
