庁 metropolitan government

Someday we'll take all the city government guys to a cave and nail 'em there.

metropolitan government ★☆☆☆☆
都 (major city) + 庁 (metropolitan government) = 都庁 (metropolitan government)

metro police ★☆☆☆☆
警 (the fuzz) + 視 (peer at) + 庁 (metropolitan government) = 警視庁 (metro police)

regular uniformed city cops (as opposed to local cops or specialized cops like 刑事　(けいじ, meaning detectives), FBI, etc.)
