News gathering in real time was messy in 1963, just as it is today. The people we revere for their roles in telling the tale of that day were making the sausage live, and you can see all the glitches and confusion play out as more facts get handed to them.

Maybe I'm getting cynical, but a JFK/9-11 sized story now would be cluttered with "instant analysis" and posturing. Plus a ton of stammering and eyebrow frowning.

I'd be glad to be proven wrong, although I really don't want the nation to go through that type of disaster again.
