Imagine a police officer arresting you for the crime of selling “drugs”.
Later in court, the judge asks you how you plea, to which you respond, “Innocent your Highness! For I am a drug dealer. I was just doing my job. My boss, Pablo Escobar told me to do this. If you guys don’t like us doing this, apply for a job at our drug cartel, work your way through our system, and persuade Mr. Escobar to change his policy.”
This is no different in principle than, “I’m a cop, just doing my job destroying food that homeless people need because politicians or a police chief told me to do so. Don’t like the law? Work through our system to change it on our terms.”
Same goes for “I don’t make the law I just chose to take this job and enforce the edicts.” Or, “I’m not congress, I just invade countries and kill civilians when I’m told to.”
Cops would never accept such a ridiculous excuse from us, let’s stop accepting that immoral pathetic excuse from them.
