The legacy of Stephen Lawrence’s murder, 30 years later 4:54
Apr 22, 2023
Thirty years after the killing of Stephen Lawrence in a racist attack, institutional racism remains a problem within the Met. It took nearly two decades to convict two of his attackers. Official reviews over the years pointed to the problems and the Met’s culture of denial. But for the families of victims of police force, accountability and justice remain elusive. CNN’s Katie Polglase reports.
A woman has recalled a "bizarre" exchange she had with serial rapist cop David Carrick - where he sent her photos of himself posing with a police firearm. See SWNS story SWSYcarrick.

The source says she was 'baffled' to see a message from a random phone number meant for a woman named Carol over a decade ago.
