Doreen Lawrence: 'Police probe failed' The mother of murdered black teenager Stephen Lawrence has attacked the original police investigation into her son's murder, saying that detectives "failed miserably" to find his killers back in 1993. Speaking outside the Old Bailey after a jury found Gary Dobson and David Norris guilty of the murder, Doreen Lawrence said: "Had the police done their job properly, I would have spent the last 18 years grieving for my son rather than fighting to get his killers to court." She thanked jurors for returning guilty verdicts, but insisted it was not a cause for celebration. These verdicts will not bring my son back. How can I celebrate when I know that this day could have come 18 years ago if the police who were meant to find my son's killers (had not) failed so miserably to do so?" she said. Mrs Lawrence also warned against using the convictions as evidence that racial discrimination in Britain was now a thing of the past. The fact is that racism and racist attacks are still happening in this country, and the police should not use my son's name to say that we can move on. Stephen's father Neville said he was "full of joy and relief that two of my son's killers had been convicted" in a statement read out by his solicitors. "They will be sent to prison and face the consequence of their actions," he added. Gary Dobson and David Norris will be sentenced on Wednesday.
