Exxon Valdez oil spill
commenter "William_Shatner" alleges, on 2009-04-17:
The cover story was that it was about one drunk captain -- who was inexpensive and easy to scapegoat. The real problem was, that Exxon agreed to install radar systems and collision avoidance within the Alaskan preserve area. They were given a naturally protected and deep port location -- worth millions, for next to nothing, in exchange they would have the latest safeguards and hire local indians. Of course, they turned off the safety equipment and fired the locals after a few years and went back on every agreement of safety and standards.
After fighting and delaying and watching indigenous people go broke and move out of the area, Exxon saved much more money than they would have spent complying with their safety agreements.
