As others have already said here, more is needed.
I think another proper move would be to abolish police unions - nationally. This coming from a pro-union individual; however, these organizations have failed the public in my opinion.
And it's not really their fault. Unions are tasked with strictly defined goals around protection/advancement of wages, hours, benefits, and working conditions. To fail to advocate for these on the behalf of their paying members - opens them up to lawsuits themselves.
Ideally there would be an organization that would stand up for the protection of the individual in police organizations, the current structure(s) we have in place simply are not congruent with respect to protection of both the working individual in an organization and the public at large.
