Things like this just don't happen. How long have there been oil platforms in the gulf, yet suddenly two just explode within just a couple months of one another!? Oil rigs are a LOT more stable that THAT.
With ALL the inspectors from the state government, federal government, corporate, insurance companies, and the oil rig manager all cracking down on rig safety and maintenance, how the hell could this POSSIBLY happen!?
The first rig explosion might have had a mechanical malfunction, but this second one has GOT to be sabotage, plain and simple. Probably ELF or some other leftwing extremist group. But the federal investigation will not go far enough to figure that out, at least not officially.
And yes, I wouldn't put it past the ELF types to do something like this. Yes, they'd possibly be damaging the environment, in a limited area, and for a limited time. But keep in mind that all the oil spill cleanup equipment is still not very far away. The ecological damage would be very limited, yet the larger impact would be felt in the oil industry. The more of these things start blowing up and leaking oil, the more likely the federal and state governments will ban offshore drilling completely.
