Ahh! Hide the doughnuts!
My 2 cents: I also think it's accepted in american english to say "the police is coming" and is in my opinion what is most commonly said. "The police" designates a group of undetermined people.
Do you speak American English? I'm an American, and I'm not familiar with this usage.
I would not say that. Police refers to multiple officers. If one officer is coming, I would say "the officer is coming".
I agree that the correct answer in English is that the police are coming - at least colloquially.
Funny thing, I heard sirens outside when I did this question.
"The police is coming" should be accepted (Baltimore)
