I guess I live in a different world. I have run multiple large beer events. (4 or 5,000ppl at the last one) These get approved by our city and state. All I have ever been asked is if we have a security plan, not any details, just that one exists. And it's sort of in passing, usually after the we need a copy of your insurance requirement. There were not any requirements to hire an officer. I still choose to hire 3 off duty officers but that is my choice as the event host. I also call them individually as I have met many of them over time and they are worth every penny. They aren't even expensive compared to other services required.
