I don't know. The police force in America has failed time and again to treat matters fairly as it comes to racial equity. I don't know that you get actual change without structural revision. AFAIK from the article it wasn't talking about getting rid of the police department, just massively defunding it.
Even though a racial crime is what sparked all of this, as we address concerns about policing, other shortcomings like mental health and sexual assault (both female and gay) issues can/should be addressed as well
