And that no one really expected they were looking at the end of civilization or something that required gluing yourself to the TV to learn more about. And that by the time they did realize the situation was serious, the government and media were gone and there was no more information to be gotten.
Rioting across the nation along with reports of violent cannibals seems like something that's more important than what most people focus on. I mean, right now you can have a guy that kills a lion get national attention, and of course riots in Baltimore, etc, get lots of people's attention despite that there's not nearly as much damage there, and on such a wide scale. I think the above comparison to 9/11 would be apt too. The death toll in the first few days would certainly be a lot higher, but not enough for the news to stop broadcasting.
Realistically there is no reason for these characters to have missed the news. After Cal was run over, they tried to listen to the radio, but there were oddly no reports of it, as Nick noted. But they didn't try anymore after that. Why not? It just doesn't add up and points toward what I said, that the writers don't want to elaborate on the outside world to aid in their plot. They wanted to keep these characters in the safe zone naive, even if it didn't make sense.
Well, look back to the original Night of the Living Dead
I think it was able to avoid it because it was a different era of communication and a rural area. They didn't have to get into specifics really. And the Dawn remake didn't really explain much either. Yeah, they had some news reports, but that was really it. Of course, those movies don't have the luxury of time that a series has. I was kinda hoping for a slower burn in the first season of FTWD, although I guess six episodes makes things limited. I wasn't expecting things to be so close to where TWD started by the end of the season.
