Washington Journal, September 10, 2010:
Ocean Springs, MS caller:
(At 1:50 in) But there's one thing I'd like to ask BP.
They're putting monitors on these life vests, that just started yesterday.
Nobody knows what these monitors are.
I think they're air monitors to see if the fumes are coming up from the oil, but nobody really knows here what they are. They're not telling anybody.
