Police....

Prahari, if I remember correctly, in Nepali.

American (and English) English = Pigs.

If we are on animal names: poulets in french (or volailles, schmitts, bleus, and far more desultory terms...)

Is that current British English, go_2? i don't think it's current American. I hear Five-Oh these days, although there's a good chance that an slang term I'm familiar with is obsolete on the street.

Micolett, in the US in the past there was "bull", which I believe was borrowed from German.

I thought it had died out, Vinny, but heard it again a couple of weeks ago.

"Rozzers" is still current as well on the eastern side of the Atlantic, I think.

American (and English) English = Pigs

Not everywhere.

London -- Bobbies, or Peelers after Robert Peel, or The Bill.

Cops.

In many languages it's the same or almost the same (in Dutch: politie, Indonesian: polisi, Afrikaans: polisie).

In Lao it's tamluat.

In Greek, it's Astinomia (as-tee-noh-MEE-a)
