I think the oil rig disaster, and the mine disaster, involving large corporations, with very bad track records of safety, is going to get looked at very hard.
I understand that mistakes get made, and things slip through the cracks, but it appears to me, that these companies have made systemic bets, that they either won’t get caught, or the fines won’t be that big, and that the pursuit of profit is worth more than the potential loss of life in a “worst case scenario”.

I’m all for profit, but you have to be prepared for a “worst case scenario”, and BP was not. Now, they were following the law, here in the US, but they could have done more. At the least the “shells” to collect the deepwater leaks, and the booms to collect & burn off the leaks, should have been sitting in a warehouse, IN CASE they were needed.

My 2 cents, are worth what you paid for htem.
