Did racism really have anything to do with George Floyd's death.?

The cops kill people and as a society we like to pretend that they only kill black people despite the fact that the VAST majority of the people that are killed by the cops. Its ignored when the victim is not black. While they were rioting in Ferguson after Michael Brown was killed a black cop shot and killed an unarmed white kid names Dillon Taylor in Salt Lake City. About a year before George Floyd was killed a white man name Tony Timpe was killed in the exact same way. There is a video of him on the ground crying, saying that he could not breath while a cop was kneeling on his neck, and then he died. The only difference is that George Floyd was black and Tony Timpe was white. If George Floyds death was caused by racism what about Tony's? When the exact same thing happens to non-black people how can you justify blaming racism when it happens to one person and ignoring it when it happens to another. In 2020, 780 non-black people were killed by the police. Other than the color of his skin what justifies claiming that racism played a role in George Floyds death?
