Don,
"he has repeatedly characterised the whole Pakistani culture as "slightly predisposed "
No I have not.
The cultural explanation is not mine.

"He ignored also the fact that the 29 percent of British Pakistanis who live in the South do not exhibit any sign whatever of this predisposition."
I could speculate but without evidence what would be the point?
I neither know nor care.

"He will not accept that the authors of the Dando report clearly stated that they were worried that some people were drawing from their report, the erroneous conclusion that this was (as Keith insists) a new crime type."
Not true.
I have accepted that.
I have only ever referred to their conviction stats.
I said it may not be a new crime type, but it is a crime.
