The point of abolishing police isn't so that nobody shows up when you call 911. It's so that the right person for the right situation shows up when you call 911.
Given the current state of American policing, there is only one situation where I would call the police, and expect the right person to show up.
That situation is an active shooter. For nearly everything else, I don't need an armed-to-the-teeth, compliance-at-gunpoint, qualified-immunity-protected man with a gun to show up. He is not the right person for 99% of the work the police currently engage in.
