He's a military vetern and would not be quiet because he says his loyality is to our country, not to BP. Some will claim he is only talking like this to get even with BP for firing him, but that is not true. He got fired for speaking about this and documenting it on film.
This incident is short on details but this might have to do with unpublished reports from residents who have caught BP spraying corexit at night over people's houses which is very dangerous to human health and life.
This report also answers questions people have who claim they never hear about any of this in the news.
Looks like it will be a series of interviews. The first video interview is at the link.
Why would they do that? The oil is in the ocean or on the beach.
That's one side of a story that is lacking in details. I have no reason to believe he is lying, and his service to our country does earn him some benefit of the doubt. However, even if he is telling the truth, it doesn't mean he was right. I'd like more details, and if possible some independent verification of his claims. If they sprayed the stuff over people's houses, wouldn't there be some evidence of that?
