Nobody? A majority of Americans would disagree with you. This sounds like an unfortunate incident, but in a nation of 320+ million people (of which roughly 1-1.5 million are LE of some type), there are millions of interactions between police and non-police citizens every single day. Only a tiny, tiny fraction are this negative.
Where are the “good cops” turning over the “bad cops?” They could do a lot of good for the whole country if they would tear down their Blue Wall of Silence.
Remember the saracen cop that fired his weapon right in front of his partner’s face, in the car, murdering an Australian woman? Why didn’t the partner say anything? Maybe he did, and it wasn’t disclosed, but we don’t know that.
