Yeah, I know. Of course BP is saying, “no one could have predicted.”
Of course, BP had a big incentive not to predict these things: one of the reasons it was able to get an exemption from an individualized Environmental Impact Study is that it estimated the largest possible spill from this well to be 162,000 BBLs, making it less than the 250,000 BBLs estimated in its regional drilling plan. You see, BP had an incentive not to predict this catastrophe.
Update: See ThinkProgress’ compendium of “No one could have predicted” claims from early in this disaster.
