Soon to be the largest oil based mistake in history.
One which has basically destroyed a region.
Yes, caution about other rigs is important. The laws won't help here. That's not why they were shut down. It's that there still is no contingency plan (as is evidenced by BP not having corrected this) if a mistake happens by another company. There's nothing.
There was no evidence that we knew of in March that this mistake would happen. It did, there was no back-up plan, there was no clean-up plan, there still is no solution 50+ days after it happened.
The problem isn't that the rigs aren't in compliance with law, the problem is that if there's an accident (unforeseeable) or another mistake...then we have 2 items gushing with no solution.
