I think ALL of the reporters down there are IN THE WAY unless they use their communications to get those in charge information about where help is needed. Thise Remote TV units are very self-sufficient with their own power and real time communications.
Shep WAS doing some good work there for awhile trying to get someone to realize there was some folks in dire straights at his location.
Now he is just there. They need to get more info out, hell get a damn flatboat and get some video intel of some of the folks trapped in those projects nearby and even take some out if they can get close enough.
These folks he was spotlighting according to another reporter came from the Superdome because they didn't want to go to the Astrodome. Why didn't we hear that from Shep?
