Imagine this scenario:
It's 1823. You're a black man - a slave - living and working on a plantation in Indiana owned by Mr. Reeves. You live in the barracks and work in the fields with 24 other black men. Do your job well and you'll make it through the day without punishment. Do your job poorly - or worse, get caught doing something unbecoming a man of your lowly station - and you'll feel the sting of a whip (or worse!) by sunset.
And so it goes. Day in and day out, this is your life.
One day, a fellow slave named Jacob approaches Mr. Reeves, the plantation owner. He convinces "The Mister" to hire him as his de facto slavemaster. Jacob explains that he'll watch the other slaves for Mr. Reeves. When they get out of line, he'll carry out their punishment. For doing this job, Jacob explains, he requires a daily wage of $1.30 and selected perks.
You're horrified at Jacob's betrayal. It would have been bad enough had Mr. Reeves simply chosen him for the job. But Jacob actually applied for the position and then sought payment for it. You resent him.
A week passes and your resentment is as strong as ever. One day, Jacob approaches you and says, "Charles, you failed to pick through 12 acres today. For that, you shall be whipped. However, because I am a generous man, I will allow you to wear your shirt while I whip you. You are welcome for my act of kindness."
Is Jacob, the betrayer, the jackal, the hired thug who sought a position to wield power over others, deserving of any less disdain?
No.
Cops apply for positions that give them authority over me. And they do so knowing they are paid with monies taken from others under the threat of violence. They may be "good" people, good fathers, good brothers, and good husbands. But if I come across one that is bleeding out, I will keep walking.
