In 2018 49 police officers were killed on duty in the US, how many riots have started because any of them were killed?. How much sympathy do their families get. If it was a white man died during an arrest there would have been no riot, whites are involved in criminality and are handled in exactly the same way as Blacks or Hispanics - with extreme caution.
We’ve seen so called race riots in the U.K. it’s an excuse for the criminal underclass to exploit the breakdown in law and order. There is no doubt that drugs play a big part in criminality and a large number of arrests are high on drugs which makes the person irrational violent and very difficult to subdue and secure. Every police office knows the very last thing you want to happen is for someone to die in your charge, black or white, because the consequences are severe. This case was not racism, it’s exactly what causes a riot which is to be avoided at all costs, many others have died in the riots, not to mention looting and other criminality.
Even in the UK there is open hostility to the police and other public services, anyone in uniform. It’s not just ethnic minorities it’s across the population, the real divide is between the “haves and the have nots” and the uniforms represent the “haves”.
