I would suggest that there is a problem with different levels of criminality in various demographic groups, though to say so publicly could get you in hot water (we have stats for this in the US - not sure about the UK).

For example (and this is just my personal observation), knife crime in London is overwhelmingly carried out by young black men. When I was over in England last month I watched a new/talk show about this... it didn't take long for 'white people/society' (social injustice, deprivation etc) to get the blame, and no one in the studio batted an eye -also, when the police stopped and searched young black guys for knives, it was decried as racist. In almost the next breath, the same people complained the police weren't doing anything.

Multiculturalism is a bitch of a challenge.
