A tent is a hazard?
I think the theft as destruction was criminal. There's nothing wrong with having a fire in the tent. The frie marshal should have just made a rule, or had the police enforce an existing rule, which would have been with a ticket. They should have been arrested if there was a problem.
"Municipalities condemn and knock down homes all the time."
After due process of law and compensation has been given. They don't do that by making up their own rules!
A tent which has an open fire with a person in it is always a hazard. But then you cannot possibly be uneducated enough not to know that. Or can you?
