In Texas there are laws specifically outlined to protect burn bosses. They are a licensed person by the state. I was just at a class for CEU credits last month. We all sat through several hours of a legal section.
It may be different there but I stand by what I said. If the forest service did it nothing will come of it. As long as you have you permits, burn plan, adequate personnel, call it in, are with in the burn parameters, and what ever else hoops you have to jump through it will be near impossible to prove criminal negligence.
It's totally different is Billy Bob Rancher or Farmer just goes out and lights a fire.
