It took them years, years to do something, it was investigated but charges were dropped last year, no one went to jail for endangering thousands of people and possibly killing a few. Also that this even happened is because of a lack of investment, propper oversight, and well safety standards, because safety standards that can be ignored by officials aren't worth the paper they're written on. Generally speaking, their safety standards are shite and the ones they have don't get properly enforced. Look at fracking and the natural damage that's involved with it, their roads and bridges, their electricity network, their dams and dikes, and so on, the list is almost endless.
That country only works because they managed to indoctrinate themselves with one message: US #1. Oh, and of course because everyone has freedom, that includes dying to the most basic stuff that's practically outlawed in the western world. This shit wouldn't fly anywhere else that calls itself a representative democracy.
