Another one might have taken this opportunity to start an in-depth "investigation" (read "bullying spree") to figure out who sold the beer and who bought it and passed it on (if anyone in that bunch might plausibly have been underage.)
About a helicopter, the problem is compounded because that whole outfit needs some quota of flying hours to remain certified. It might be a boring area, and any opportunity to take it out and fly then counts as training, if nothing else can be written up for that flight. That there is a helicopter guarantees that it will be used. And same for SWAT and such.
The helicopter will go and respond to random calls if it’s not needed for anything in particular.
Not defending the practice, just explaining why a helicopter might respond to something that’s overkill
Sometimes it would follow you around with the spotlight until a squad car came and pulled you over and accused you of a crime which a similar vehicle was involved with. In my case, the not-me truck was illegally harvesting rock from a park, but my truck bed was visibly empty from the sky so I don't know why they bothered summon the car.
Fixed wing planes like Cessna 172s are in the ballpark of 100/hr.
