The question isn't usually about the raw numbers--you just count, and go, "Oh, yeah, larger fraction."

The question is about why.

If black people are more likely to be poor, and poor people are more likely to commit crime, and criminals are more likely to be apprehended by police and sometimes get shot, the entire situation can have nothing whatsoever to do with police bias.

You need to intervene at the level of preventing poverty, in that case.

Alternatively, if black people are suspected by police, stopped by police, the situation is escalated by police, and then they're shot by police, the entire situation has everything to do with police bias.

In that case, you need to intervene with the police.

The distinction is immense. If we don't understand what's going on, we can notice that there seems to be a problem, but we're unable to fruitfully intervene.
