“appears to me that the knifers are white-on-white British killings”

In fact it’s primarily black youths, wounding and killing blacks, whites and others in the UK. Tony Blair, speaking at the end of his period as Prime Minister:

“Tony Blair yesterday claimed the spate of knife and gun murders in London was not being caused by poverty, but a distinctive black culture… He said people had to drop their political correctness and recognise that the violence would not be stopped “by pretending it is not young black kids doing it”.

Giving the Callaghan lecture in Cardiff, the prime minister admitted he had been “lurching into total frankness” in the final weeks of his premiership.

Of course British liberals are not ready to see what is in front of their eyes. From the same article:

“Mr Blair’s remarks are at odds with those of the Home Office minister Lady Scotland, who told the home affairs select committee last month that the disproportionate number of black youths in the criminal justice system was a function of their disproportionate poverty, and not to do with a distinctive black culture.”

This will all of course be very familiar to an American audience.
