True, but systems can change, and only individuals can change them. If anything I’d say we ought to acknowledge and laud cops with good intentions as examples of what policing should become (as opposed to what it has been and too often, currently is). From your perspective — and you were quite explicit about this at the end — the entire system is the problem, which leads me to two possible paths forward: reform the system or burn it to the ground. The latter seems appealing, but history shows us it isn’t and that — even when done out of good intentions — that many people will suffer.
Reform, while slow and painful, does not have to be as violent and can also lead to real change. Acknowledging that there are “good cops,” and that those men and women strive to protect the peace and uphold stability and justice is an important ideological counterweight to the narrative you’re laying out.
Certainly agree that the $100 billion you’re mentioning could be better spent, but abolishing the police is likely to end up costing more than the $100 billion that would be saved. Let’s start by cutting some of that cost by de-militarizing the police which will simultaneously address at least a few of the problems you have identified and laid out.
