I did not read it.
But if a court didn't agree after weeks of expert testimony, why should I stick my head in?
Where I am disagreeing with you is whether this should be a tort law issue, or a regulatory issue.
Tort law (if I understand correctly) could address issues AFTER THE FACT, whereas the regulatory/supervisory regime is about avoiding (or minimizing) the tragedies.
The penalties for not providing/maintaining adequate safety procedures, training, etc. should be steep, and include jail time in certain instances. If the owners/managers of the plants reported in the article were to face mandatory jail time, I am sure the working environment would turn much safer (or we would lose the jobs to countries where human lives are unimportant, and it's cheaper to do business, unless we enforce it throughout the supply chain down to the consumer product).
