The Investigation Channel (ID) on cable has a show called "Fear Thy Neighbor". Most episodes end badly. The police are always called, its a he said/she said, sometimes cameras are used as evidence, but mostly, the guy with the gun ends up going to prison, and always, both families are destroyed.
The potential for conflict resolution exists, but seems to elude both parties.
There are neighbors who get into peoples faces given any perceived injustice, imagined or real. Mostly, it happens when they are seen with a beer in their hand, go figure.
When crazy knocks on my door, (it has happened), the police are notified. There is a RING doorbell that captures movement.
My drone experiences with the public, so far, have always been positive. When reading up on the local, state and federal ordinances, new restrictions are learned that were unknown before. In McAlester, Oklahoma, there is a "fence law" that states its illegal to fly above a property if the property has a fence. (A few years back anyway, maybe its changed now).
Anyway, good luck, stay safe.
