I lived in a small city. Everett WA, that experienced a series of arsons. 1992-1993. 76 fires and two deaths in one year. He got life of course, but I have an opinion as a result. I can add it was very difficult to sleep during this ordeal My point is that all arsons, including some without any mortalities should be categorized as serious as first degree murder. An arsonist knows the potential for deaths is always possible. Deaths without motive, the arsonist does not care. They are terrorists without a motive.
