"These young men are in a western society, in any event, they act like any other young men, they're fizzing and popping with testosterone, they want some outlet for that, but Pakistani heritage girls are off-limits and they are expected to marry a Pakistani girl from Pakistan, typically," he said.
"So they then seek other avenues and they see these young women, white girls who are vulnerable, some of them in care ... who they think are easy meat." - Jack Straw

A couple of stories for you related to the above:

1: Bus journey in Derby in the late 1960s with my father-in-law. A group of six quite boisterous youngsters, all male, who I took to be of either Indian or Pakistani descent were on the bus. as female passengers got on and off the bus their was a constant stream of conversation within this group. after a while my father-in-law got up from his seat and went up to them and spoke to them in flawless Urdu telling them that he knew where they lived (Of course he didn't, but they weren't to know that) and that their parents would be ashamed of them if it was reported to them what they had been saying about the female passengers on the bus. He then told them exactly what he thought of them, using the terms that they themselves had used in insulting the passengers on the bus. That is when I learned that from his time in India and Burma with the Army during the Second World War he had learned to speak Urdu, Pashtu, Hindi and Nepali - all fluently. I had never seen such a shocked look on the faces of complete and utter strangers in my life and from that moment onwards they were totally silent. Their view of "western women" was exactly as Jack Straw described.

2: In an Pakistani owned Indian Restaurant on the south coast in the mid-1980s with a friend of mine who had been born in Bombay, worked in India pre-partition in Karachi and then firstly in East and then in West Africa, and was now retired. We were half way through our meal when he asked the waiter serving us to get the owner, who came over. My friend then asked the man to call three of the waiters over. He then proceeded again in perfect Urdu to tell the owner how these three men had been referring to the his female diners during their service. He also told the owner that if he did not reprimand them there and then in the restaurant he would report the matter to the police. The reprimand was given and at least three tables in the restaurant that night got a big surprise when they found out that their meals were strangely "on-the-house". The views of those waiters on "western women" was exactly as Jack Straw described.
