Referring to the murder of Stephen Lawrence in an open letter to Commissioner Bernard Hogan-Howe, Dr Richard Stone, a former member of the Lawrence inquiry panel said:
Here we are 14 years later with the worst kind of blatant and violent racism by police. Even worse is that the officers appear to be doing it openly in front of colleagues from whom they have no fear of being reported.
Such a group of constables could not be routinely racist like this without their seniors being aware, and telling them to stop. I fear this may alas be more than 'just a few bad apples'
