ROFLMAO - that'll get the cops sicked on him for sure!
OK, I'll throw in my $.02 worth.
I'll have to start with a personal belief that will factor into what I'd do here. Animals do not have the value a human life does. I know this 'cause I eat 'em!
Seriously though, I don't believe they do, so...
1. If family was with me, wouldn't have stopped in the first place. Gone on til out of sight and called Police. Fido is toast.
2. If I was alone and
had stopped, per your narrative, I only hope I would have been sane enough to keep a lot of SA and make sure he was alone. Now, taking from the point in your narrative, I'm already involved as I told him to stop. He proceeds toward dog with lighter. I'm going to stand right where I am and watch him. Either he goes through with it with a witness or he backs down. Lets take the first. Fido flambe. I'm sick that he did it, dog is screaming, he's sick
because he did it. If he leaves, render aid to, or put down dog. Call cops, give statment, go on way, mourn fido. If he sticks around, I leave, call cops, tell them I'll go to scene of crime once I meet them at some nearby point. Then I'll give them statement and be a good witness etc.
A. I would not intervene further. This dude is sick and who knows if hes armed or may have other sick friends hiding in the weeds. At this point I'm OK with defending myself if aggression appears from the other(s) but I'm not going to start it. He hasn't threatened me.
B. I would not get on my cell to call cops at the scene. For one, we're in the country. They are many minutes away. For another, he might find that act provocative. I'm sure flame boy would know I was calling the cops on him. I'd rather attempt to leave gracefully.
My actual reaction would have been to drive on by and call cops, meet them there, be good witness, etc. There are some things I'd risk getting shot over but a dog that isn't mine is not one of them. Some of this also depends on the odds. If it were me and 5 buddies and just him alone then hell yeah I'd have done more. It'd be risky even then and I know it's stupid, but at least we could have come at him unarmed first to try to stop him. It would be a risk I'd be willing to take with enough backup. One on one, too dangerous, period.
Oh, I suppose the bit about the burn ban could give you justification to draw down on the SOB since he could conceivably be getting ready to start a brush fire that could kill people. I honestly don't know if I would have even thought about that at that moment though. Given that I wouldn't have probably thought about that, I doubt my actions would be different.
