To me this makes far more sense than a indiscriminate defunding. It’s what I’ve been advocating for. Defunding the police by itself doesn’t solve the problem. Firing crooked cops does to some extent.
And in the case where crooked cops have infiltrated the department to the point where it's effectively impossible to fire just the crooked ones, shut it down and start over. Or do something better and call it "police" so that the pearl clutching causes less nerve damage.
