I think that the people that test and build the machines are responsible. The machines should have worked no matter what, even if the workers didn't interpret the warnings right. The machines should have been able to stop all of the oil from spilling. If the machines had worked then most likely the spill wouldn't have happened or had as big an impact on the environment. I think justice for the people that made the machines would be around a year in jail. It seems harsh but the oil that was spilled had a huge impact on the environment, especially the sea life around the spill. The spill affected businesses that relied on sea food and many animals were killed or severely injured.
