This is a bit of a non-sequitor.

"21 times greater" is a great sound-bite but I honestly don't know what you'd expect. Take white males, make them 10 times as likely to be killed in general, 5-10 times as likely to be murderers, make them stronger, more likely to come from extreme poverty, give them a 50% high-school graduation rate, increase their rate of illiteracy, increase the rates at which they carry deadly weapons, increase how often they are violent in general, increase their sense of despair and hopelessness, break their family structure so many of them turn to street gangs for acceptance and give them a culture that openly glorifies violence against the police.

Now they're still white males, how much would their chances of being on the losing end of a violent confrontation with the police increase?

In other words there are many other causes and conditions that are at play here and assuming it's because cops are racist is absurd.
