Do you think the train wrecks in the US are accidents or sabotage?

Accidents as they are subsidized and protected by paid off politicians. That is one reason why the pipelines have been stopped as people like Warren Buffet who owns Burlington Northern bought politicians to stop the pipelines that are a much safer means of transporting oil, gas and other liquids except ethanol which there is not a safe way to haul it for any distance in steel containers or pipes.
