"It can still be informative to describe aspects of a culture, and British Pakistanis are a very culturally distinct group."

Indeed, the study of culture can be very interesting and informative, not to mention useful in learning to understand culture.

But it is important for you to be sure you have explored the subject properly and learned to understand it fully before you start quoting academic papers that you haven't fully taken the time to digest as evidence to support hypotheses concerning the causes of crime.
