How to say "cop" in Japanese

• ポリ
  nounA colloquial, derogatory abbreviation covering both the police and a police officer. Because it expresses contempt, it is not a neutral way to refer to an officer.
• おまわり
  nounA colloquial word for a police officer, usually written in kana alone. It fits casual conversation about an officer; its tone is informal rather than insulting.
  お巡まわりがやってきたぞ。↗

  Here comes a copper!
• ザコップ
  nounNot a word for a police officer at all: this is the Japanese title of the film Cop, so it belongs only in talk about that movie.
• マッポ
  nounSlang for a police officer. It belongs to casual speech and can sound disrespectful, so it is seldom the word you want in neutral contexts.
• 気候変動枠組条約締約国会議きこうへんどうわくぐみじょうやくていやくこくかいぎ
  nounUnrelated to police officers: this is the name of the United Nations climate change conference, the sense in which English uses the abbreviation COP, so it matters only when writing about international climate talks.

To translate 'cop' for a person, choose among the colloquial 「ポリ」 (derogatory), 「おまわり」, and slang 「マッポ」 depending on how informal or negative you want to sound; 「ザコップ」 is a film title and 気候変動枠組条約締約国会議 is the UN climate conference.
