As the accident with Floyd showed, you don't need to fire guns to cause massive protests.
And the current data shows that black police officers are far more likely to choose dialogue over violence to diffuse a situation.

if the police in general maltreats blacks, so black policemen are also held responsible for such malpractice.
This makes no sense. If I go out and shoot a black man, does that mean that all white males of Italian descent are held resposible? All police should be held accountable, that's one of the main tenents of police reform. Transparency of the service records so that all officers, white, black or otherwise, male or female, are held accountable for their actions, and can be taken to task when their actions lead to bad situations. We don't have this, at this point, mainly because of agreements between municipalities and police unions. Derek Chauvin had 18 prior misconduct complaints before he killed George Floyd. One of the other officers involved had 6 such complaints. And yet, nothing happened except a minor slap on the wrist. This is one of the root problems with the police force in the US....little accountability for its' actions.

And that is why he was buried in a golden casket?
What is this fixation with the manner of George Floyd's burial? Extravagant? Perhaps. But how about these:

According to Celetis Memorial Spaceflights, a company that offers the postmortem flights, a low-orbit journey that lets your cremains experience zero gravity before returning to Earth starts at $995.

Dedicated space-lovers can have themselves launched to the moon or into deep space for $10,000 and $12,500, respectively.
Ground Control to Major Tom........

Do you remember that ther was no racism in the USSR and all people were proclaimed equal? Moreover, the Soviet ideology contrasted the free Soviet society where all were treated the same with capitalist countries that were grounded on oppression of other races in colonies and metropolis.
Is this meant to be sarcastic, or are you referring to a particular time period of Soviet history?
