The African-American community has spoken up. It has yelled. It has screamed. It has spent years – decades, in fact – fruitlessly pleading with the rest of the US to take its suffering seriously, and to believe its complaints of double standards in the country’s criminal justice system.
Those pleas have been met with indifference, scepticism and in some cases undisguised scorn.
Rioting and violence are always to be condemned, of course. Yesterday Mr Floyd’s brother Terence issued an admirable call for calm.
“It’s OK to be angry. But channel your anger to do something positive,” he said.
“(George) would want us to seek justice the way we’re trying to do. But channel it another way. The anger, damaging your hometown, it’s not the way he’d want.”
Former vice president Joe Biden, who is the Democratic Party’s nominee in this year’s election, struck a similar tone.
“We are a nation enraged, but we cannot allow our rage to consume us,” Mr Biden said.
But most of the people marching through America’s streets are not setting buildings on fire or seeking confrontations with police. They’re protesting peacefully, in greater numbers than ever before.
And what other choice do they have? Nothing else has worked.
Freddie Gray died in Baltimore after sustaining injuries and falling into a coma while in police custody. None of the six officers suspended from their jobs in connection with the incident were ever convicted.
In February this year, 25-year-old Ahmaud Arbery was chased down and killed by a white father and son while he was out jogging. No arrests were made until May, when video of the shooting happened to emerge.
Last month a white woman, Amy Cooper, called the police and told them an “African-American man” – emphasis hers – was threatening her life because he had asked her to put a leash on her dog in Central Park.
And of course, police officer Derek Chauvin jammed his knee into Mr Floyd’s neckfor almost nine minutes, slowly killing him, even as members of the public filmed the scene and the victim pleaded for his right to breathe.
There had been 17 complaints against Mr Chauvin during his policing career, by the way, which resulted in two letters of reprimand and nothing more.
These are not isolated incidents. The same things have been happening for decades. The difference now is that everyone on the street has a camera, so we all get to see the incontrovertible proof of wrongdoing.
Without that footage from bystanders, Mr Floyd would just be another sad statistic; one more dead African-American suspect among thousands. White America, as usual, would give the officers involved the benefit of the doubt, and nothing would change.
