The police are the bad guys no matter what so why try?. This is a low level crime. The new normal is evolving. I suggest neighbors talk to their neighbors and tell them to knock it off. The fire department should have roving patrols to handle this fire danger and life safety. No one is blowing each other up so police are not needed. I repeat...talk to your neighbor. no one is going to do your dirty work. don't call 911 and be anonymous stand for something. Seems like this is the perfect training wheels

Don't Enforce
First you say this a low level crime so the police shouldn't bother. Then you say it's a problem of fire danger and life safety. Which is it Don't Enforce? You can't have it both ways.
The fire danger is tantamount to arson and the life safety could result in manslaughter or murder charges, not to mention the victims' critical burns, anxiety, loss of limbs and death. I say go after the culprits hard, then hit them with big fines, public service and jail time. Don't Enforce, if someone sets off illegal fire works which destroy your home you can pat them on the back.

Whatever: I suspect Don't Enforce's irony may have been a bit too subtle for some to pick up on, but it is there if you look closely. Self-policing is hard to do, but is inherent in the broadly-advocated call for "defunding" to keep the potential for escalation to a minimum. I think Whatever is suggesting this might be an opportunity to try it out.

It can not be that hard to identify where the fireworks are being set up and apprehend the people. Why not use our over-budgeted Fire Department and their Drone to fly over the area any evening and find the places setting them off and capture footage of it. Then the police can respond without sirens and make some arrests and confiscate fireworks. It does pose a serious fire threat so they would be justified in helping out.

The Fire District's Drone Policy quite properly prohibits their drones being used for law enforcement purposes.
