Earlier quoted context omitted.
The article you linked draws more of a link between income levels and police violence than it does race. They explicitly say that the crime rates of low-income neighborhoods, populated by majority minority groups, are higher than that of more affluent neighborhoods. Furthermore most of the injuries happen when the person stopped has a gun, regardless of race. Not great, and certainly unacceptable, but not equivalent…
if you want to deny the lived experience of african americans in the US, you're free to do so (it falls under free speech) but frankly I think making ivory tower-level statements like this ignores an extraordinary amount of evidence that african americans (and many non-caucasians) experience systemic racism that affects their economic opportunities and health.
On another note, when did Caucasian become a term for white people? As an actual Caucasian, having immigrated to the US from a region near Caucasus, I don't get why people use the term so loosely. The debate is about skin color, just use skin color.
