I tried to mention Dalian Atkinson as anotehr victim of terrible policing - a British one at that- yesterday. I had half (selective half) of Wikipedia quoted back at me and was told he was a 'violent criminal'. I am still angry.
There is definitely a sub section of society , seen on MN, who only care when a white person has been a victim of police mishandling (and in Atkinson's case manslaughter).
