Caught or arrested someone, or obtained/took something (British slang), or admitted to something ('copped a plea').
From Old French 'coper' meaning 'to strike' or possibly from Latin 'cappa' (cape/cloak). In modern slang, probably influenced by 'cop' as a verb meaning to catch or take.
The origin of 'cop' (police officer) is debated—it might come from 'copper' (the metal buttons on early uniforms), 'constable on patrol,' or Latin 'capere' (to catch), making it a perfect word for someone whose job is to catch people!
