Will "Black Lives Matter" Matter?

I have a problem with the BLM movement.
Don't get me wrong---black lives do matter. So do all the other lives, if "mattering" means "should be equal before the law." To put it in different words "legal rules should apply to all people equally." This is in contrast to "different rules for different people" a formulation that violates Kant's Categorical Imperative.
Back to BLM. Their movement is based on the premise that the main problem with the American justice system is racism.

Now even if the cops weren't racist, would qualified immunity, no-knock raids, the drug war, the paramilitary structure of police forces, powerful police unions, incarceration, and military equipment for internal policing thereby not become a problem?

Qualified immunity makes it nearly impossible for an LEO to commit a tort while on the job.

No-knock raids make it impossible for a citizen to know whether they're being raided by the police or attacked by criminals.

Incarceration of non-violent criminals, usually for offenses against drug laws, result in flagrantly disproportionate punishment at the expense of the taxpayer.

 The paramilitary structure of the police encourages a military-type esprit de corps and feelings of loyalty among LEOs to each other (as opposed to their putative employers, the taxpayers, who they typically refer to as "the little people").

Powerful police unions protect their members no matter what harm they may do to innocent citizens.

Military-grade equipment is made available to municipal-level police forces for "crowd-control" purposes, but also used in military-style assaults on private residences(!}

So, no, even if the police administered their injustice without regards to race, there would still be injustice!

What are the BLM asking for in concrete terms? Nothing. Nothing concrete is being asked for. They're just saying "racism is wrong." What does that mean to the system? The system already acknowledges that racism is wrong.

Unless they start thinking more deeply about the problem, I think nothing useful will come of all this sound and fury. And that would be a pity.
