> Second thought: why arrest a guy for simple property damage? A hundred dollars damage or so. Isn't that a civil case?
First, intentional damage to or destruction of property is different from "simple property damage" and is usually criminal for the same reason other intentional acts depriving an owner of their property (e.g., theft) are.
Second, in many places discharging a firearm is generally prohibited except in specifically enumerated circumstances where it allowed. (Its a very common prohibition in urban/suburban areas.)
