Imho, the DEA agent in question is not the cellphone guy. The way it looks, the cellphone guy was contacted by the DEA agent. (see Greta's interview of Charles Croes, he states that he was contacted by a friend. My assumption is that friend was the DEA agent). Also I believe that particular DEA agent has been on O'Reilly a couple of times early on in the case. His name escapes me at the present. I will have to look it up.
you can call and ask him
and the hotties can also call him :)
