A whistleblower told Anderson Cooper that BP is using Corexit to sink the oil and therefore covering up the size of the spill:
In a shocking interview with CNN’s Anderson Cooper on June 29th, Allegiance Capitol Corporation V.P. Fred McCallister said that BP is deliberately sinking oil with the toxic chemical disbursant Corexit, to hide the size of the oil spill. By sinking the oil before it can be collected, BP won’t have to pay fines on it.
McCallister said, “Everybody in Europe, where the standard practice is to raise the oil and collect it, is scratching their heads, and quite honestly laughing at what’s happening in the Gulf.” He added, “Everyone is looking at us and wondering why we’re allowing this to happen.”
They're pumping the dispersant directly into the gusher using several different tubes and contraptions. It's a criminal cover-up happening in plain sight.
