I suppose it might help if I answered my own questions...
So who did the best job? Who are you watching?
CNN mostly. Generally speaking, I like their news coverage best, and their hurricane coverage has become particularly good. Anderson Cooper is wonderful (I dunno why I like him so much, but I do). I thought it was interesting that they called in reporters who were experienced at covering refugee situations in other countries, and then had them compare and contrast what they were seeing in New Orleans.
MSNBC was my second choice.
And of course, I kept up with local news, to keep informed about the evacuee situation here in Houston.
Do you think the media exaggerated things?
Not intentionally. I do think there were times when they were too quick to jump on a rumor ... but considering the conditions they were reporting under, I think thats understandable. Other than that, I respect their effort to be everywhere and show us everything. This is something that America needs to see, for many reasons.
Was it appropriate for them to get emotional, or to get tough on officials?
Well, the short answer here is a definitive YES. The long answer goes something like this....
The media and the powers that be (local, federal, government, private sector) are supposed to have an adversarial relationship. A reporters job is to uncover the things that the powers that be want to keep under wraps. Unfortunately, in a lot of ways I think that has fallen by the wayside. Reporters don't ask tough questions in interviews anymore. They let press secretaries and PR people push them around. They have gotten really, really lazy - they take everyone's word as gold and run with the wire story without even thinking twice. I guess that keeps the contacts happy with you and all - but doesn't it kind of defeat the purpose of a free press?
This time, though, the discrepancies between the official word and the reality on the ground were too great for reporters to ignore. How could they tell people that "things were under control" when they were standing in front of a mob of thousands of people crying out for water and food, some of them dying on the sidewalk right in front of them?? I don't know if it was emotion or just the realization that the gap between truth and reality was THAT WIDE, but reporters from all news agencies started acting like REPORTERS again.
I don't think I will ever forget the exchange between Cooper and Sen. Landrieu....it must have been sometime Thursday.....she was prattling off a list of politicians she wanted to thank for being of such great help, while we all knew exactly what was going on in the city......Cooper interrupted her and asked her how she could be patting her politician buddies on the back while he was standing just feet away from a human body that was being eaten by rats, and while thousands were dehydrated and starving.....that, and other moments like that (there were plenty), were real turning points IMO.
Reporters were no longer afraid to ask the tough questions, and ask them until they got answers. And they are still doing it. I hope it lasts. It will be one small good thing to come out of a disaster...
Did they help more than they hurt?
I think my previous answer kind of gives me away here....

Yes, they helped way more than they hurt. If they werent on the scene showing us exactly what was going on, we would have had nothing but press conferences to go on....and we wouldn't have had a clue.
