Citizens, of every race, need an impartial officer to protect and to serve their needs. However________FULL DISCLOSURE: I am a combat veteran who was hired as a police officer upon returning to civilian life. I speak from experience. I left the force after seeing racism and favoritism rampant in Southern police forces.
I would be surprised if you were the only one who has quit the force out of disgust of the racism/favoritism that seems to be running rampant.
A pity, since I'm sure these folks are always hoping for an officer who is impartial, and will come to listen to their side of the story.
I would hope that maybe then, racists who antagonizes occasions like this might find themselves in handcuffs, rather than laughing from the sidelines.
Or maybe I'm just naive, since I don't know how the dynamics work between different police officers who have different points of view.
The dynamic is that any officer who violates the "blue wall" or "blue code" by pointing out the bad behavior of another officer is shunned, berated, locked out of promotional consideration, etc. Often, those of us who have faced this leave the force. That or they become quiet and, therefore complicit in the bad behavior. The citizenry is then left at the mercy of the bullies in charge.
That is why, as much as I loved police work, I left to become a bodyguard. I was paid 4 times as much, traveled the world for free and enjoyed a much easier life.
