One rather interesting aspect is that the guy who was leading them around the marshes told Billy that they were under orders not to try to save any animals.
They were supposed to call a special phone number with a GPS coordinate for the animal, and "eventually" someone would come de-oil the critter. Of course, the implication is that nobody ever shows up , and in any case the animal would be long gone by the time they do. Even though he was told he would get into tr9ouble for it, Billy managed to save a raccoon and get it to a cleanup center.
There is a new reality show on A&E called "Billy the Exterminator", and while I don't think it will have the legs that "Dog the Bounty Hunter" has, last night they did a special show on the destruction in the Louisiana wetlands in which they went deep into the marshes on air boats and saw how bad the damage is.
There is no way that the oil has simply "gone away" between the time they shot the episode and last night when it aired. I could see from the editing this one was rushed through post.
But the point of all this is, the claims that the oil has just gone away is purely a political exercise to limit BP's financial liability in the case, and to save the Democrats in November.
