The 0 regime in DC does not want the US to develop it's own energy resources. However, when gas goes over $4 this summer, the political pressure is going to be high to "do something".
No better way to take the wind out of the "drill here, drill now" crowds sails then this "accident". So even if it was terrorism, the DC clown posse are never going to look for it. They want it to be an accident so an accident it will be.
Obama's response will be the same as last time, "Inflate your tires."
