He understands that you will immediately come over and kill him and everyone he loves if any harm comes to your people?

That can be communicated nonverbally.

just joshing.

everybody thinks they drive safely and it’s the other guy who is nuts.

maybe the way to win is to outgun nut the gun nut.

automatic weapon fire holding down your perimeter.

joke. justa joke…

more conservatively, it might have some effect to have an attorney right a letter saying, hey, normally if someone got hurt from your gunfire in aresidential area, you probably would not be charged criminally, cause you’d get to claim it was an accident.

But since youre on notice by virtue of this letter that your shooting is dangerous, we will be aggressively pursuing murder charges if anyone is harmed. Go throught he potential penalties for various intentional weappons crimes, and fines associated with them. serve him and family personally wiht notice. this way he has a much less persuasive “it was just an accident ” defense.

on the downside, might be contrary to the negligence agrument you’d need to make to collect on the insurance policy…

kind of obnoxious, but less obnoxious than automatic weapon patrol by your border.
