There's a video of Geraldo Rivera and Shepard Smith begging the local (and perhaps state) authorities to let people get out of New Orleans over the Crescent City Connection. The shoot date is Sep. 2, and it appears both were near the Connection.
Geraldo refers to the Interstate and a WalMart on the other side of the river, and says there are thousands of people there.
Shep refers to a "checkpoint" at the Connection, saying it's the only way out and that "anyone who walks up to it is turned around".
This is much more believable than the NYT or the socialist version, but neither reporter mentions shots being fired, how many police there are, etc.
