Michael Moore ruffles feathers for a living. He’s made films critiquing America’s permissive gun culture and the expansion of the military industrial complex under President George W. Bush. On Thursday, Moore again stoked controversy by calling for the disarmament of all American police officers and the release of all prisoners serving time on drug-related convictions.
