Unless the "illegal activity" is occurring in or near his driveway, I don't think so. My camera would never capture it. He might send one of his children to fight for him (I could have him for lunch myself, 1 on 1), but I don't think so either. Besides, I believe he knows (or suspects) that I EDC. He does not (NY Liberal). Only one family on my cul-de-sac knows for certain that I EDC. And that's because they do as well.
In general, he's not really a bad guy, save for the issues we've been having of late. And, during earlier times, we were actually "friendly" with each other. But for the longest time, he's been wanting me to remove the big tree on my front lawn because he's tired of having to rake the leaves that fall on his property. He even tried to "gaslight" me once by claiming that the tree's roots extended under a different neighbor's house (not his) and caused damage. Well, 1) The tree is big, but not that big as for roots to extend that far; 2) They'd have to dig up concrete driveways, etc. to prove they came from my tree (and no one has done that in my neighborhood); & 3) Even with all that, FL tree law is on my side. As long as the tree is alive and healthy, anything that emanates from it (leaves, branches, roots underground, etc.) are the responsibility of the landowner on which they fall, not the tree owner. Even if a hurricane were to blow it over and onto someone's roof, the tree owner is still not responsible., if the tree was alive/healthy prior to the storm. Only if the tree is dead, does the tree owner have responsibility to get red of it before any damage occurs. Apparently, he doesn't understand how that FL law works. If my atty has to explain it to him, he (atty) will bill him for that! And, to be fair, I do keep it trimmed and maintained so it won't blow onto anyone else's roof.
What's been happening lately is that he's been blowing his leaves (after they leave my tree), in part, back onto my property and into my driveway, where I then have to take care of them. Not all of them, but just that portion that's near my driveway or the common grass swatch near the street. The remainder of the leaves he actually does blow into the street. I don't do that. I blow them (both mine and his) onto a central pile in the middle of my driveway where I then vacuum them up with a leaf vacuum. I already have a PTZ camera at the top of my roof that shows him doing it when he's close to my driveway. But its view is limited. I was looking to install an additional one that's closer to the ground and in the direct line of sight to his driveway, but high enough that he'd need a ladder to go up and take it down. I figure, if he knows I'm watching, he might not be so quick to blow the leaves back onto my property. I have the new camera but not installed it yet. We'll see. I'll consult my lawyer about it when I see him next on general stuff.
Nonetheless, I still have the question about everyone's non lethal weapon of choice for other incidences.
