I have family on the Coast, some of whom know folks involved in this effort, and NONE have mentioned anything that looks like that. Were some of those shots supposed to have been of the shore, covered with oil? If so, I don’t know of any shoreline on the Gulf Coast that looks like that, so that’s why I’m suspicious of it.
The footage appears to be relabled footage from a Greenpeace produced film that is a few years old.
