I think the behaviour of CKs family and friends could well have contributed to the sort of rioting we saw in 2011, where 5 people died, many more were injured and much damage was caused in a lot of communities. It was right that his background was made public quickly after Martyn Blake was acquitted.
People are doubtless mourning him, but deflection from the fact that he was a fairly senior gang member, driving a car which had been identified in 3 shooting incidents in the last few months and crying foul on the police for their reaction to the situation that he caused helps noone. Gangs are wrong, county lines are wrong, protection rackets against innocent refugees are wrong. He was involved in all of these. He was on a bad path. He was not Stephen Lawrence or Anthony Walker, innocents who died because of racism.
I don't believe that his family and friends were unaware of his (very recent ) activities, some of which had resulted in imprisonment, which they would have fully known about. He wasn't a "good boy". He was a gangster who exploited others. That would be true if he was black or white. The police saw a man trying to make a run for it (and we can now speculate as to why, a possible attempted murder charge from a few days earlier) in a marked car that was associated with shootings, who then rammed them repeatedly.
Please tell me why they should have acted differently, how much leeway has to be given to anyone who behaves as CK did that night, with the knowledge about that vehicle that they had.
