The family of Stephen Lawrence are this week to mark 10 years since the publication of the Macpherson report.
The 18-year-old's death, the landmark report and its painful aftermath changed the landscape of policing and race relations in Britain beyond recognition.
Government ministers and senior officers have overseen a relentless drive to erase the tag of "institutionally racist" from the Metropolitan Police and other forces.
But many continue to question whether people can ever be treated equally, regardless of their race or religion, by the police or within the service itself.
Doreen Lawrence will join Justice Secretary Jack Straw and Scotland Yard Commissioner Sir Paul Stephenson at a conference to mark the anniversary.
The central London event, organised by the National Police Improvement Agency, will examine what progress has been made over the past decade.
A-level student Stephen, 18, was stabbed to death by a gang of racist thugs as he waited at a bus stop in Eltham, south-east London, in 1993.
Retired High Court judge Sir William Macpherson delivered a damning assessment and made 70 recommendations, and his work is seen as a defining moment in race relations.
The most powerful criticism was a verdict of "institutional racism" within the Metropolitan Police and the service generally.
A decade on, senior officers, politicians and interest groups continue to struggle with the challenges of eradicating lingering discrimination. A £100,000 review of race and faith at the Metropolitan Police heard evidence from its first witnesses last week and will report back in the summer.
