The Guardian article you "quoted" from professor also stated quite clearly that 95% of people on the Manchester Sex Offenders Register were WHITE.

The Asian population of Manchester is 6.5%

Understanding from YOUR quoted article the Asian population, together with the Afro Carribean and Oriental population make up 5% of offenders.

What reason can you give us for the over-represented number of WHITE offenders.

I shall look forward to your prevarication.
