For those who aren't aware, according to wikipedia:
# cops per 100,000 population
534 Spain
516 Russia
465 Mexico
456 Italy
422 France
362 Northern Ireland
336 Germany
318 Scotland
279 Isle of Man
265 Ireland
239 United States
211 England and Wales
As for all the other socialist democratic countries, the former communist countries, the peace-loving countries, pretty much all the rest of them also have more than 239 cops per 100,000.
I hardly think we're over-policed.
