I'm watching the coverage on Fox News. Two things I noticed about it:
1. At one point, about 10 minutes ago, the on-air journalists were expressing too much excitement, to the point where we were commenting: "They're really getting off on this." Shortly after that, they toned it down. I assume someone told them to make it more solemn and respectful.
2. For about the first 20 minutes that I was watching, there was not a word about the cause of the collapse. I was surprised they weren't even saying that they didn't know the cause, and there was no speculation about whether it could have been terrorism or even any statement to the effect that there is no evidence that there was terrorism. Eventually, they said that they had heard from the Department of Homeland Security that there was no sign that this was terrorism. This made me think that there must be a news policy not to talk about terrorism except as fed information from the Department of Homeland Security.
