// I think the police are making quite an effort to find the murderers of Stephen Lawrence //
The police were shamed into making a proper investigation only after a campaign by the Daily Mail.
from 1998:
// One of the highest ranking officers in the Metropolitan Police told the inquiry into the way the killing was investigated that his force had "let down" the Lawrence family.
Assistant Commissioner Ian Johnston told Stephen's father, Neville Lawrence, he was "very, very sorry" for not bringing the killers to justice.
"Mr Lawrence, I wanted to say to you that I am truly sorry that we have let you down," he said. //
