I don't know where the law is that says that police are not legally required to 'help' anyone. But it's there. It's an old law on the books somewhere. Since police are not required already, and since they are really supposed to be 'peace officers', what's the big deal about this? Get rid of them, at least as they are in their current 'policy operations' status. Then, strap on your guns and protect yourself until you can organize a form of police that is legal and does its work right.
