Why are there only a couple or so videos taken from inside the Superdome during Hurricane Katrina?

From my knowledge, roughly 10,000 people took shelter in the Louisiana Superdome when Hurricane Katrina roared ashore. But yet, there are only one or two very short (1 to 3 minutes) videos on YouTube that were taken inside the Superdome at the height of Katrina, especially when the roof started tearing open. With no less than 10,000 people, I would have figured somebody would have brought a personal camera or iPhone with them and taken much longer video of the storm as especially the eye wall hit and the wind started tearing away at the roof. I mean, lots of people even bring personal cameras and iPhones to a lot of events held at a stadium such as Ringling Bros. And Barnum & Bailey Circus and Disney on Ice. If I were there, I most certainly would have videotaped Katrina's effects on the Superdome from within. And especially as even a group of storm chasers brought their cameras with when they sought shelter at the Mississippi Coast Coliseum near Biloxi.

If over 10,000 people sought shelter in the Superdome, why aren't there more or longer videos taken inside the stadium as the storm hit?

Maybe people are worrying about their own lives and their loved ones? Maybe there are more videos but it hasn't been uploaded to youtube?

Quite a few years ago, video wasn't as common then.
