This is a good one. The 100,000 acre Hayman fire in CO was started by a forest ranger. The same one who reported she got the license plate number of the possible fire starter as he was speeding away (turns out he was a nearby resident who found the fire and was going to report it). This ranger started the fire to burn a letter she was upset about. She went away and came back and it was out of control. When she couldn't get it contained, she lied about how she found it and who started it. She is currently in jail and in big trouble.
