It sounds like you got your answer, but if you'd like more Harry Potter practice in Spanish, there are several Flashcard sets here on SD that have to do with Harry Potter and other magical words.
Could it be hipocresías?
As nballen suggests, I believe it's a deliberate misspelling of "policía" for comic effect, since the Wizards are not familiar with "muggle" institutions like the police. Hence, the "please-men" in the English version.
