I wouldn't feel bad about calling the police. Clearly something was going down that you don't need next door to you.
Is it possible to open up a good neighbor conversation with the father?
We've always had good relations with the father. My husband had spoken with the father about the young lady's boyfriend wandering onto our property. My husband was very nice about it and it was appreciated. Later, the father spoke to my husband and said he had spoken with the boyfriend. Apparently, the boyfriend had moved in without permission, etc, and was talked to about that as well as trespassing. So, we do feel comfortable approaching him if there is a problem. The father does have a temper though, so we are very careful.
We haven't complained about all the equipment (like bulldozers, old lawnmowers and such), empty trailers ands sheds, and trashed out cars on his property. We live in a rural area and if you can't see trash from the road, then you're ok. However, he's had as many as 15 vehicles in his front yard. One can see a lot of the crap from the road but we don't complain because he's a pretty nice guy. The rest of us have nice farmhouses and well-kept lawns and so forth. Our properties are not zoned for multiple family dwellings at a single address either. I believe he has four different families at that property. We let it go. The family has been here for a long time, too.
I don't know much about police procedure and don't know if they would have arrested someone for disorderly conduct (like yelling and cursing at a police officer) or if there were drugs involved. In this case, it may have been both.
None of the people living on that property are too swift. They just aren't very bright. The landlord's girlfriend told my daughter that she almost shot me twice while she was hunting. Number One, I was on my own property walking my dog so what the heck was she doing hunting on my property? And she almost mistook me for a deer TWICE? Needless to say, we don't go near the back of our property during hunting season.
The young lady that lives in the trailer with her parents (she's 17 with one child and has another on the way), had told my daughter she couldn't wait until my daughter was driving so she could driver her to her uncle's meth lab. She thought her uncle having a meth lab was sooo coooool.
The county we live in is widely agricultural. My husband is an engineer, works in a different county. Our county has the most meth labs of any county in NY state. In my naivete, I was surprised. It's such a quiet place - in many ways, the perfect place to raise children...as long as you manage to stay away from the redneck drug traffickers.
