The fires can be arson, and this footage can be fake. They have nothing to do with one another. It would be a lot easier to catch arsonists if they were flying helicopters because they would show up on radar. Any fires started by the road could be done easier without the drone. Why would you fly the fuel up just to drop it back down next to you?

Areal dropping of fire only makes sense if you are trying to start fires in remote areas that can't be reached any other way. Places far away from roads. That is the opposite of what we are seeing.
