Angela Davis is responible for the slogan and when she said it she meant de fund the f*cking police. The population would be better off without them.
It's the slogan of an anarchist. Someone who believes that we could rule ourselves better without rulers at all and that we could police ourselves better without police at all.
But slogans are not policy. They are hyperbole meant to shock people into action. Apparently it worked, you centrists have been figuring out the best ways to reform the police and changes are already underway.....
The slogan cost democrats nothing in the election and may have saved some lives already. That's why we have activists, slogans, and demonstrations, because y'all would sit on your thumbs forever unless someone demands action.
