What I remember that was a policial or investigator that was in a crime scene and found that one suspect was in the public, and he couldn’t arrest him because it was against the philosophy of anarchist or some shit, and when running behind the suspect he could walk in the street because it was funded by public money, I think I read it here on Lemmy, but I can’t find it lol
I wonder if you’re not thinking of the L.P.D.: Libertarian Police Department bit, because eg. the publicly funded sidewalk thing sounds very familiar:
I put a quarter in the siren. Ten minutes later, I was on the scene. It was a normal office building, strangled on all sides by public sidewalks. I hopped over them and went inside.
Not anarchist though, but your description sounds like it’d match
