A N WILSON's account of the racism still present in public schools is shocking ("Why the Lawrence Five take me back to public school", 11 April). Such harassment and bullying would never be tolerated at my children's schools, here in the heart of a multiracial city. It is intolerable that such attitudes should be allowed to prevail among such overprivileged children, many of whom will go on to hold positions of power in government and society. Head teachers who fail to tackle these problems are guilty of collusion. For the sake of all our children it is time public schools were abolished.
