The DEW shit is getting annoying and once again making us look crazy. Cut down a live tree and throw it in your fireplace and watch what happens then try a 2x4.
CA created the conditions for a fire to spread like crazy and a fire was either started intentionally or accidentally. I wouldn't be surprised if it was on purpose but all you need is a match.
Using some fancy high tech weapon is a great way to have it tracked back to you when a simple match will do!
