Fed. Scientists Request More Info From BP & Are Ignored

I just saw a piece on CNN Wolf Blitzers "Situation Room," where one of the scientists appointed by the federal govt to make an independant accessment of the true rate of flow of BPs undersea gusher was on, and he said that the figures they arrived at (as indicated in the article in the link below) were basically based on wide ranging approximations because their request to BP for more information has gone unheeded and he says, lacking that information, they can only guess at what the actual flow rate may be. Why wont BP release the relevant info to the federal scientists so they can do their job and tell US what the real rate of flow is? What could they possibly have to hide?
