And they shouldn't be. But there is a very large difference between 'mistakes' and 'intentionally circumventing processes put in place to ensure safety'. Having to draw lines is always difficult, but in this case the line has been crossed. Consider what Martha Stewart went to jail for, then compare to what happened here. If justice is to be observed as even handed there ought to be some serious consequences here, not some already rich guys getting richer with their golden parachutes, the irony of which I'm sure will not be lost on the relatives of the people who died.
