Not overheated, but you need to learn how to talk to cops.
The first step is get him on record: 'Can you put that in writing sir' (the sir is important, you don't have to mean it.)
Then ask to speak to his supervisor.
If he gives you any answer but '(s)he will be hear as soon as reasonably possible' politely order him off your property.
You don't want to touch him, he'll shoot you, get away with it and get a medal.
Also bear in mind it could be a rent-a-cop. They tread very close to impersonating an officer on a daily basis.
Finally consider you might mess up a good thing. The fireworks might be too close to your house. Making too much noise could end the display for everyone.
That's what's been mostly on my mind. I should like to enjoy next year's show.
