And particularly the frightened people in the 'Dome and Convention Center should have been kept off air?????

Did you read this part?

NOPD Capt. Jeff Winn's 20-member SWAT team responded on about 10 occasions to calls from the Convention Center, usually after reports of shots being fired. The group found people huddled in the fetal position, lying flat on the ground to avoid bullets or running for the exits.

and this?
Some, however, did report seeing armed men roaming the building, and Fore said he heard gunshots in the distance on at about six occasions

A lot more corroborative info in there that you do not mention in your familiar effort to blame everything on the media.

One thing you can predict with accuracy: people struck with a disaster will tend to exaggerate or even actually to perceive things to be worse than they are. Body counts will fluctuate. You will always hear numbers bigger than the actual numbers when the facts come out.

And when recording testimony from humans, you have to take into account human nature. If you want to avoid that messy human nature thing, then you have to toss out all testimony.

Man I love this game you always play where, after all the facts are known, you go back and pick apart all media coverage done before the facts were known.
