All cops are not working to risk their lives for their local, state, and federal governments. Most are working for a paycheck with benefits. Most operate under the guises of fear, racism, hate, or frat mentality. They are never going to think the way your article believes they should. The ROI is zero for police. My partner is a cop, and she is retiring this year. She has never shot anyone. Arrested lots of criminals who have broken laws, but never killed anyone. She’s never been put in a position where she had to consider it. Police are trained to kill, and make split second judgement calls on what they see based on real or perceived threats.
Many cops will never admit they fear people. The others will never admit they hate people. The few good cops never admit the other two groups exist among them. That’s the problem. Then there’s the snitch code and rally regardless policy cops have. It’s sanctioned and paid for by taxpayers. If people would withhold their payroll taxes, I bet you’d see change quickly! If money isn’t withheld until the behavior changes, these types of killings will continue.
