A hand full of people say all cops are evil, and you immediately assume that all the people in the area agree with that. Where are you any different from them?
Of course they don’t all agree with hating the cops. But those who don’t need to speak up and loudly say that violent anti-cop rhetoric and advocacy has consequences and will not be tolerated in their community.
The cops pulling out of certain communities might edge that realization along a little bit, to make the point clear for everyone who might be sitting on the fence or who might not want to get involved.
To have a safe and vibrant community, people have to get involved. They can’t just take things for granted. Good policing requires community support and involvement.
