1) The people with the power over the police have almost no contact with the people being policed. Neighborhood schooling reinforces that problem. It ensures that ability to afford housing segregates black people from white people. (Note: it’s not a question of funding. Here in DC, most of the shiny new LEED Gold schools are 99% black. Therefore, white parents won’t send their kids there, notwithstanding the gleaming facilities and lower housing prices in the surrounding area.) School choice gives black people the power to create integrated schools, instead of waiting for statistically wealthier whites/Asians to get woke enough to want to do it. I think people would be much more sensitive to policing issues if they didn’t just hear about these things a couple of times a year on the news, but were faced with people in their PTA suffering the consequences of police brutality. I would add that, unsurprisingly, a decisive majority of black people support school choice.
2) With notion of black people being “the other” rooted since childhood, qualified immunity and police unions eliminate the near term, immediate consequences of acting on those instincts.
The two things that make people think before they act are empathy and self preservation. The libertarian approach is a double-barreled solution that could hit both.

It touches on two NYC schools that share a building (The Earth School & PS64) but have remarkably different racial and socioeconomic makeups. I found it fascinating after touring Earth School earlier this year.
