Do I know how these fires started? No. Do I think that if they do discover how they started it will lead back to some nutty brainwashed liberal trying to shine a light on global warming? Yes. Time will tell. History doesn’t always repeat, but it does usually rhyme.
In a way, it doesn't even matter what started it anyway. You leave that much tinder and kindling lying around piled up, it's going to catch sooner or later.
Though anyone who did set fires should definitely be prosecuted.
