Research by Scotland Yard published in a London newspaper, has proven that knife crime
in London is a serious non – white phenomenon, with 165 of the 225 under- 18s accused of knife crime in the past three months being from the black or other non – white groups．
According to Scotland Yard, only 60 of the 225 crimes were white．Despite being a small minority of the knife holding criminals, whites did, however, make up the single largest group of victims of knife crime．
According to t
he Scotland Yard report, whites made up 222 of the 637 victims of knife crime over the last three months．This number could probably be higher, as 292 victims were not identified by race．
This month Scotland Yard Deputy Commissioner Sir Paul Stephenson suggested knife crime has replaced drug selling as the top concern 
for London police．
Sir Paul said so as he announced a specialist knife crime unit to deal with teenagers carrying knives in the capital．It will use a team of 75 specialist officers to find criminal group members and their supporters．
Detective Inspector, George Rhoden, president of the National Organisation of Black Law Enforcement Executives said, “In the black community we have all noticed that there is major concern about gun and knife crime．Clearly we are not the only part of the community affected by the problem of children who have no fathers, but parental responsibility should be of major concern.”
Around 59 percent of black Caribbean children and 54 percent of mixed – race youngsters are looked after by a lone parent．In the white British population, the number is 22 
percent．
