The issue isn’t even just “crime” in the sense of robbery, etc. When there is no police, organized crime can take over. When we lived in Bangladesh in the 1980s, a minibus full of criminals showed up at the gate of our house. (This being Dhaka in the 1980s, we had a brick wall around the whole house with broken glass on top and a big metal gate, and an armed guard out front.) I don’t know if it was because my dad hadn’t bribed the right people or what, but it took police an hour or more to respond, during which time the criminals tried to drive through our gate.
(I don’t actually disagree with the thrust of the article, which is more that we need to rethink the roles where we have police. I’m just sharing this because I’ve seen a lot of “defund the police” in my Facebook, and I strongly suspect it’s from people who have never lived somewhere without effective policing.)
