Source etymology 1

Original entry ↗
noun

Police or law enforcement, collectively.

Selected source glosses provide context, not a complete modern definition inventory

Of uncertain origin. Widespread use of the phrase as an anti-police slogan grew following the 2014 killing of Michael Brown in Ferguson, Missouri. * Possibly from 1312, an alternative form of ACAB (“all cops are bastards”) in which the letters are substituted with their position in the alphabet. * Alternatively, from the American police procedural television series Adam-12 (1968–1975), in which 1-Adam-12 refers to a patrol unit and its radio call sign. Likely popularized by "F*ck 12", a song by American hip-hop group Migos from their 2013 mixtape Y.R.N. (Young Rich Niggas), which uses 12 in reference to the police while describing a narcotics raid: “12 kickin' in my front door […] 12 in my home, they won't leave me alone”.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
