Looks to me that nobody at Malheur had violent intent (despite media allegations).  Certainly not compared to the law enforcement folks, who are armed to the teeth.  Those worried about cost might consider how much money the feds are now wasting with all the resources committed to finding the smallest details that might support criminal charges.  I suspect that objective damage is minimal and full restoration would cost substantially less than the current and ongoing investigation.  When they lock up all those people, we the taxpayers will be paying millions of dollars in taxes to keep them in jail for the decades that the feds will likely push for.
