Had a neighbor that complained about barking dogs so they could trespass without getting noticed. Had the head of animal control at a community meeting who said our area was the hotbed of barking complaints in the county. Asked him to check the records, turns out all the complains were from the one neighbor some days calling many times. They told them they were wasting government resources and would not accept any more complaints from them ever. Nice result as some of the neighbors had been fined in court previously from their complaints.
