Wait, what? Take a second look at the first 3 paragraphs, and then the "Racial Patterns" section of that Wikipedia article you linked.
When people say that police killings aren't racially motivated, they are disputing the causes of the disparity in race-based deaths, not the disparity itself.
I mean, you can just do the math from recorded police shootings yourself, and you pretty consistently across multiple years get death-per-million numbers for black communities that are around 1.5-2.5x as large as for white communities. Black men are pretty objectively killed at higher rates than white men, the studies you're talking about are questioning why that is and whether officer bias and/or systemic racism plays a role in those numbers.
