It's not an all or nothing thing. It's about moderation, and right now, there is no moderation of policing. Thinking in absolutes is where you're wrong. You don't see people calling for fire departments to be defunded, right? There's a reason police departments have come under scrutiny, and it's because they are out of control. When the people tasked with your protection have no accountability, they always trend towards tyranny.
Fortunately, there are an infinite number of control points between what we have now, and the world of Mad Max. The goal is to get things back to an appropriate level for all races.
