Alison Saunders, Chief Crown Prosecutor for London, said: ?The Crown Prosecution Service brought this prosecution after a lot of hard work and scientific developments. We have worked very closely with the police throughout their investigations and with the Lawrence family to bring these killers to justice. ?This is one of the most significant cases of this generation: changing attitudes, policing and the law. It has taken a long time and a lot of hard work to get here. The prosecution took the exceptional step of making an application to the High Court to quash the acquittal of Dobson and order a retrial. We were convinced that the new and compelling evidence presented by the police was strong enough to successfully prosecute these individuals. The High Court agreed with the application for a retrial. ?It should be remembered that 18 years ago, a young man lost his life. We hope these convictions will offer some justice to the family and friends of Stephen Lawrence. The family of Stephen have long campaigned for justice to be done in this case and I would like to pay tribute to them for their perseverance and determination in this matter.?
