Actually, it's funny that this was brought up. A little backstory into what has transpired recently.
Over the course of the last few months, my neighbor had been picking fights with the 27 year old guy whose parents live on the other side of him (separated by a walkway). Finally the guy had enough of it and went after my neighbor. Nothing physical transpired because the guy's dad jumped between them, but later that day my neighbor went to his Jeep and pulled out a rifle and brought it in the house. The guy was sitting on his own porch at the time and the neighbor stuck his head out the door and formed a gun with his thumb and forefinger (like a child would) and goes "BANG! BANG!" in the direction of the guy.
The guy's parents called the cops because they had finally had enough of the neighbor and state cops and local cops showed up in droves due to the involvement of a gun and "threats" if you want to call them that. After the police showed up, two citations for harassment were issued to the neighbor and the guy up the street. The neighbor decided that he was going to fight his and it went to court, where he was essentially chewed apart by the judge and was told to grow up and stop instigating fights with the neighbors. He was told that the state police and local police are tired of his antics and all it's going to take is a single phone call complaining about him acting up again and he would be immediately issued another harassment fine with the possibility of jail time.
So, basically, lightening his wallet by $1200 and the installation of security cameras by the neighbor next to him appears to have taken the edge off, at least for now. Well, except for when he tried accusing me of cutting through his wall with a recip saw when we were remodeling last August. We hadn't cut a single thing and a recip saw was never even in the house during the course of remodeling, so when I challenged his accusations, he suddenly had the realization that when he moved in, his kid was helping him cut out the baseboard with a recip saw and "that must be where it's from. I should have asked him before coming to you." I mean, really, nearly a year after we moved in and remodeled, you suddenly noticed a cut in your wall when you moved the vacuum and tell me you want it fixed? - I don't think so.
So we haven't had any issues with them since that confrontation, including coal deliveries. We're just keeping our distance and minding our own. But as you can see, they still can't be trusted.
