Stephen Lawrence (13 September 1974 – 22 April 1993) was a black British teenager from Plumstead, southeast London, who was murdered in a racially motivated attack while waiting for a bus in Well Hall Road, Eltham on the evening of 22 April 1993, when he was 18 years old. The case became a cause célèbre: its fallout included cultural changes of attitudes on racism and the police, and to the law and police practice. It also led to the partial revocation of the rule against double jeopardy. Two of the perpetrators were convicted of murder on 3 January 2012.After the initial investigation, five suspects were arrested but not charged. It was suggested during the investigation that Lawrence was killed because he was black, and that the handling of the case by the police and Crown Prosecution Service was affected by issues of race. A 1998 public inquiry, headed by Sir William Macpherson, examined the original Metropolitan Police Service (MPS) investigation and concluded that the investigation was incompetent and that the force was institutionally racist. It also recommended that the double jeopardy rule should be repealed in murder cases to allow a retrial upon new and compelling evidence: this was effected in 2005 upon enactment of the Criminal Justice Act 2003. The publication in 1999 of the resulting Macpherson Report has been called "one of the most important moments in the modern history of criminal justice in Britain". Jack Straw said that ordering the inquiry was the most important decision he made during his tenure as home secretary from 1997 to 2001. In 2010, the case was said to be "one of the highest-profile unsolved racially motivated murders".On 18 May 2011, after a further review, it was announced that two of the original suspects, Gary Dobson and David Norris, were to stand trial for the murder in the light of new evidence. At the same time it was disclosed that Dobson's original acquittal had been quashed by the Court of Appeal, allowing a retrial to take place. Such an appeal had only become possible following the 2005 change in the law, although Dobson was not the first person to be retried for murder as a result. On 3 January 2012, Dobson and Norris were found guilty of Lawrence's murder; the pair were juveniles at the time of the crime and were sentenced to detention at Her Majesty's pleasure, equivalent to a life sentence for an adult, with minimum terms of 15 years 2 months and 14 years 3 months respectively for what the judge described as a "terrible and evil crime".In the years after Dobson and Norris were sentenced, the case regained prominence when concerns of corrupt police conduct during the original case handling surfaced in the media. Such claims had surfaced before, and been investigated in 2006, but were reignited in 2013 when a former undercover police officer stated in an interview that, at the time, he had been pressured to find ways to "smear" and discredit the victim's family, in order to mute and deter public campaigning for better police responses to the case. Although further inquiries in 2012 by both Scotland Yard and the Independent Police Complaints Commission had ruled that there was no basis for further investigation, Home Secretary Theresa May ordered an independent inquiry by a prominent QC into undercover policing and corruption, which was described as "devastating" when published in 2014. An inquiry into whether members of the police force shielded the alleged killers was set up in October 2015.
