Oh, a random arsonist will do. There is a firefighter above in the comments who explains how embers can start fires outside of a fire zone. I can believe the DEW theory, but I also remember the fire 2 years ago in Tahoe that was started by some crazy lady who heard voices (which might have been OP too....). It drove out a lot of residents who couldn't rebuild and freed up a bunch of prime land for redevelopment for richer types.
Hit them with directed energy weapons?

I think that DEW explains the facts and the random arsonist is just a theory.
