There are laws about negligence and inspection for utilities. There should be laws about forest management, I suppose, but the law is what determines culpability, not the cofactor analysis of the actual problem root.

In the fender-bender example, I can see how you would structure your logic the way you have. As an example of how I and others might structure it: The car causes the accident when a wheel falls off, and the accident happens to happen where there was a prior gas spill. The presence of the gas spill is unfortunate, but the car caused the accident, and that should never happen with good design and maintenance. The accident was exacerbated by the presence of gas, causing a fire and injury and death, etc.

Now, to bring it full circle. Replace a car with a train (the situation is largely under the control of a single company), the accident with a train falling off the rails and hitting a gas pipeline, AND the company knew the gas pipeline was there, and knew the danger all along, and still managed to not put on a proper maintenance plan to ensure the train didn't derail especially in a place that has a gas pipeline right there.

We are talking about what ought to be, not what is. The law falls under the category of is, and does not imply ought. I think everyone in the conversation understands that PG&E bears some amount of legal liability for these fires.
