yeah except once again you completely ignore that in the same study the police admitted the possibility there was false reporting by people as being sudanese when they were not
not to mention percentages are severely distorted when it comes to smaller populations, the New Zealand and Indian populations actually had a higher number of assaults but since they have more people in their community the bad apples are not as pronounced, again it doesn't really have anything to do with "black people being criminals" as you suggest, in fact i need not repeat that in that very study it was shown that african immigrants commit significantly less crime than non african immigrants
even if it includes white africans, they would be almost an insignificant number statistically purely due to the fact those same people were searched and stopped by police 8 times more than the rest, you think white africans would be subjected to this?
