wow. what a really bizarre thing for them to do. I guess the neighbor was filming fireworks or something and that is how they caught 'em?
if it was me, I probably would go through with reporting the incident to police and if the police wanted me to press charges for it, I guess I would probably do that. only because they were on the property, trespassing, vandalising and due to the nature of the reason they picked your house. It's kind of like stalking, IMO.
I'm only saying this because these guys probably still think they did the right thing, or they did the wrong thing for the right reasons. A little trouble with the police might actually make them understand how wrong their thinking is. Or at least, how illegal their thinking is.
As for the suggestion to send the story to a local news station or paper, it depends on who you want your audience to be. If it's believing, active witnesses, that won't get through to them. How many news stories have they heard and dismissed already? And if it's general population, how many of them would really care?
Whatever you do, or decide not to do, good luck and hope you don't have any more problems with these idiots.
You know what they say, 40 is the new 12.
