I wouldn't say there is no data needed, but lets agree if you took a poll you could quickly produce the data. There is overwhelming evidence to those that know people of color (this affects other races as well) that indeed they fear interactions with police.
Why is it an issue in 2020? Is it pure hatred, is it systemic. Really i think the police community needs to answer this question. There were 6 officers fired in Atlanta yesterday for brutality, several if not all were AA. So let's assume that maybe there is the possibility this is more than just purely racist tendencies. I am sure that is some of it but there has to be some other stuff that plays into this as well. I don't have the answer, but we need to be more intentional about understanding it so we can work on it.
