Yes. Why is this crazy? There’s no natural law that says a society needs a police force as it exists today. Police in the US have only existed since the mid–1800s. In the South, they rose from the ashes of runaway slave patrols; in the North, they were created to quell labor organizing [0]. So the issue is that police as we know it today is intrinsically racist and classist, and we need to entirely reimagine it.
This is just a perspective from a foreign country. My worry would be would I trust armed neighbourhood vigilantes more than the regular police. I dont know enough about the US, but do you think that would be better?
